GCSE Physics - Water Waves - Shallow to Deep Water
 
05:32
This tutorial is about how waves can speed up or slow down when then enter a material with a different optical density, or when water waves enter regions of different depths. This change of velocity can cause the waves to change direction - this is called REFRACTION. Subscribe for more physics tutorials like this: http://bit.ly/Subscribe-Physics-Ninja Water waves will refract when then move from shallow to deep water causing them to speed up. As a result, their wavelength will increase and the refracted ray will 'SPEED AWAY' from the normal line. Remember that the wavefronts are always at 90 degrees to the ray. Use 'RNAR' to work through the steps: 1. Ray (incident ray) 2. Normal (line perpendicular to surface where the ray enters) 3. Angles (label the angle of incident and angle of refraction) 4. Use the refraction rule "SPEED AWAY" to determine which direction the refracted ray will bend. Quick question: During refraction, the wavelength and the speed of the wave changes. What does NOT change about the wave? (Answer... the frequency of the wave does not change) So why do waves get faster in deeper water? The answer is a bit complex, but here is an explanation posted at the Illinois Department of Physics: 1. For a shallow fluid, the motion of the fluid is mostly side-to-side. 2. In order to accumulate more fluid in one place (to make the crest of the wave), each little bit of fluid must travel a little farther than it would have to in deeper water. 3. When a wave passes, the bits of fluid (if you could watch one at a time) travel in ellipses. For shallow water, the ellipses are stretched out horizontally, and in very deep water, they are very nearly circular. 4. So for a wave of the same height (top to bottom of the ellipse), the bits of water must travel farther in the shallow tray than the deep tray. 5. Because the waves of the same height in shallow and deep water exert the same pressure differences due to gravity to get the water moving (although the motion is different due to the fact that the bottom is there), similar forces push and pull on the water. 6. To get the water moving farther and faster with the same force takes a longer time for each push, and hence a slower speed for the wave which travels in the shallow water.

Gravity And Me: The Force That Shapes Our Lives (Full Physics Documentary) | Spark
 
45:15
Physics professor Jim Al-Khalili investigates the amazing science of gravity. A fundamental force of nature, gravity shapes our entire universe, sculpting galaxies and warping space and time. But gravity's strange powers, discovered by Albert Einstein, also affect our daily lives in the most unexpected ways. As Jim tells the story of gravity, it challenges his own understanding of the nature of reality. The science of gravity includes the greatest advances in physics, and Jim recreates groundbreaking experiments in gravity including when the Italian genius Galileo first worked out how to measure it. Gravity science is still full of surprises and Jim investigates the latest breakthrough - 'gravity waves' - ripples in the vast emptiness of space. He also finds out from astronauts what it's like to live without gravity. But gravity also directly affects all of us very personally - making a difference to our weight, height, posture and even the rate at which we age. With the help of volunteers and scientists, Jim sets out to find where in Britain gravity is weakest and so where we weigh the least. He also helps design a smartphone app that volunteers use to demonstrate how gravity affects time and makes us age at slightly different rates. And finally, Jim discovers that despite incredible progress, gravity has many secrets. Content Provided By TVF International.

Domino Chain Reaction
 
02:34
A domino can knock over another domino about 1.5x larger than itself. A chain of dominos of increasing size makes a kind of mechanical chain reaction that starts with a tiny push and knocks down an impressively large domino. Original idea by Lorne Whitehead, American Journal of Physics, Vol. 51, page 182 (1983). See http://arxiv.org/abs/physics/0401018 and http://arxiv.org/abs/1301.0615 for sophisticated discussions of the physics. As seen on QI in the "kinetic" episode.

Labor Markets and Minimum Wage: Crash Course Economics #28
 
10:38
How much should you get paid for your job? Well, that depends on a lot of factors. Your skill set, the demand for the skills you have, and what other people are getting paid around you all factor in. In a lot of ways, labor markets work on supply and demand, just like many of the markets we talk about in Crash Course Econ. But, again, there aren't a lot of pure, true markets in the world. There are all kinds of oddities and regulations that change the way labor markets work. One common (and kind of controversial one) is the minimum wage. The minimum wage has potential upsides and downsides, and we'll take a look at the various arguments for an against it. Crash Course is on Patreon!

Forces Can Push or Pull | Science Is A Snap | Jack Hartmann
 
02:38
Forces Can Push or Pull. Your children will learn the most important science fundamentals about forces in this super catchy science song. This song for kids about forces teaches children that a force either pushes or pulls and forces make things move. The video shows many kid-friendly examples of forces and how they push or pull things in the environment. Children push in their chairs in a classroom, pull in a game of tug-of-war, a kite is pushed by the wind to make it fly, children push and pull playground toys. All of these examples are clearly shown on this video with both audio and video telling the children if the force is a push or pull. Forces Can Push or Pull will help children clearly see how forces move things all around them. After seeing this song and video in force, teachers and parents can extend learning about science by observing all different movements in their home and school environment and decide it’s a push and pull. LYRICS: Forces make things go up Forces make things go down Forces make things go back and forth Chorus Forces make things go round and round Forces push, push, push, forces pull, pull, pull Here are some things that forces make move When you slide your chair back in place A push is the force that makes it move When you jump up high in the air A push is the force that makes you move When you come back down from a jump A pull from gravity makes you move (Chorus) When you tug a rope in a tug of war A pull is the force that makes it move When you bend down and pick up a book A pull is the force that makes it move When you fly a kite in the air A push from the wind makes it move Forces push, push, push, forces pull, pull, pull Forces make things move Forces are all around Jack Hartmann's website: http://www.jackhartmann.com Remember to connect with Jack Hartmann on his Social Networks: Facebook: https://www.facebook.com/hop2itmusic Pinterest: https://www.pinterest.com/jackhartmann/ YouTube: https://www.youtube.com/user/JackHartmann Twitter: https://twitter.com/Jack_Hartmann Google +: https://plus.google.com/u/0/111246828015196865180/posts You can find Jack Hartmann's Music on: Jack Hartmann Website: http://www.jackhartmann.com iTunes: https://itunes.apple.com/us/artist/jack-hartmann/id391057562 Amazon Mp3: http://www.amazon.com/s/ref=ntt_srch_drd_B00423GXF2?ie=UTF8&field-keywords=Jack%20Hartmann&index=digital-music&search-type=ss Google Play: https://play.google.com/store/music/artist/Jack_Hartmann?id=Ax3xg7dhdt5nx4b47dnwxjnhhhy&hl=en CD Baby: http://www.cdbaby.com/Artist/JackHartmann

Wave motion | Waves | Physics | FuseSchool

All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in their seats, only moving up and down when it’s their turn. Waves can transfer energy through solids, liquids, gases and empty spaces – otherwise known as vacuums. There are two types of waves – which we will look at in more detail in another video, but the basic features are the same. The frequency of a wave is the number of complete waves passing a fixed point in a given amount of time. This time period is usually one second. Frequency is given the symbol f and is measured in units called Hertz. Hertz measure how many complete cycles per second; so how many people in our Mexican wave stand up every second. The frequency and period are often confused. The frequency refers to how often something happens, whereas the period refers to the time it takes to happen. The period of a wave is the time for one complete cycle. So the time taken for one person to stand up, wave and sit down. This would be measured in seconds. When something happens repeatedly we say that the event is periodic and refer to the time for the event to repeat itself. The period of the earth to orbit the sun is 365 days, the period of a day is 24 hours, the period of a typical class at school is 45 minutes. Now for the wavelength… the wavelength is the distance between a point on one wave and the same point on the next wave, for example two peaks or two troughs. Wavelength is given the symbol Lambda from the Greek letter, and is usually measured in metres. Wavelengths can vary hugely in size, x-rays are very short, visible light is here and FM radiowaves are much longer. So we’ve looked at the frequency, period and wavelength so far. Let’s finish with amplitude. As waves travel, they create disturbance. The amplitude of a wave is the distance from the maximum disturbance to its undisturbed position. Think of a very flat sea… and then an incoming wave. The amplitude is the height of the top of the wave from the flat sea. In another video we’ll be looking at the wave speed equation, and connecting wavelengths and frequencies: Wave Equation For now you just need to know what these 4 keys words mean.

Ripples in the Water
 
00:15
The water has elasticity which is cohesion between the water molecules in an equilibrium state. The stone pushed down on the water, which made the water bounce back up, and then gravity made the water come back down and caused the splashes and the ripples. Gravity then acts as the force that tries to flatten the water back out. Surface tension is also another force other than gravity, because the ripples have short wave lengths.

Life searching for ripples in spacetime | Gabriela González | TEDxLSU
 
14:52
Gaby González and her team at LIGO have proven that when you search for the small numbers you can make massive discoveries - like proving Einstein’s theory of gravitational waves, which are smaller than even the smallest piece of an atom. In this talk, Gaby takes us through the process of g-wave discovery and introduces us to another small number we should be looking at if we want to continue scientific innovation: the small number of women working in physics If Albert Einstein were alive today, he’d probably be booking a trip to Louisiana. That’s because LSU professor, international award-winner and National Academy of Sciences member Dr. Gaby González is helping unravel one of the longest-running mysteries in astronomy. A native of Argentina and a graduate of Syracuse University, Gaby has worked in LSU’s Department of Physics and Astronomy and the Laser Interferometer Gravitational-Wave Observatory Scientific Collaboration (LIGO) in Livingston, Louisiana, since 2001. In 2015, LIGO detectors reported the very first recorded gravitational wave, a ripple in the fabric of space and time resulting from the collision of two black holes. This discovery proved Albert Einstein’s century-old prediction about the existence of gravitational waves. Gravitational waves present us with a new way of looking at the universe, and Gaby, along with the other researchers at LIGO, received the “2016 Breakthrough of the Year” award from Science magazine. In 2016 Gaby was named Scientist of the Year by Great Minds in STEM and in 2017, Gaby received the National Academy of Sciences Award for Scientific Discovery. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Gravitational Force - Class 9 Tutorial
 
04:49
Gravitational force is not a force of contact. Any object on the Earth or at least close to Earth, will experience a gravitational force. It is the weakest of the four fundamental forces, yet it is the dominant force in the universe for shaping the large scale structure of galaxies, stars, etc. Newton's Law of Universal Gravitation is used to explain gravitational force .The law can be explained as : Every point mass attracts every single other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between the point masses.

The Absurdity of Detecting Gravitational Waves

A head-vaporizing laser with a perfect wavelength detecting sub-proton space-time ripples. Huge thanks to Prof Rana Adhikari and LIGO: http://ligo.org Here's how he felt when he learned about the first ever detection: https://youtu.be/ViMnGgn87dg Thanks to Patreon supporters: Nathan Hansen, Donal Botkin, Tony Fadell, Saeed Alghamdi, Zach Mueller, Ron Neal Support Veritasium on Patreon: http://bit.ly/VePatreon A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible. When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

The Big Bang - Lawrence Krauss and Michio Kaku
 
50:28
Professor Lawrence Krauss and Professor Michio Kaku explain the physics behind the events in the first second of The Big Bang, events which range from the first fractions of a second after creation: The Plank Era; The field symmetry breaking; formation of elementary particles; Matter-antimatter annihilation (explained by Dr. Tara Shears); Formation of atoms and the last scattering of photons which make up the Cosmic Microwave Background (Explained by Dr. David N. Spergel) to the billions of years of stellar evolution: the formation of stars and Galaxies which developed the visible universe as seen today. Using High Energy Particle Accelerators and Observational and Theoretical Astrophysics, scientists are able to recreate the first few fractions of a second after the Big Bang, to the point of symmetry breaking, and in conjunction by using space and earth-based observatories observe the remnants of the Big Bang itself using powerful analysis of the CMB by the WMAP and Planck Spacecraft combined with the modelling of the large scale structure of the universe as done by The Sloan Digital Sky Survey.. The Initial Conditions of the Universe are still a mystery and debate has gone on recently to whether or not there were even any initial conditions at all, maybe the universe can form from no initial conditions in standard space-time and that the very fabric of space, curled up in perhaps infinite dimensions creates an infinite set of paths for scalar fields to branch off of and interfere to create the flow of energy from the initial big bang. Such a theory is predicted by M-Theory, which gives the Multiverse picture of curved Space-Time in 11 Dimensions which, through quantum mechanics, create many scalar fields that couple at different strengths in each universe creating a different set of physical laws in each universe. Not all universes could be suitable for life, each universe seems to have the Planck Constant encoded into it, as it is the Uncertainty Principle and the Sum over Histories that lead to the Multiverse picture in the first place, however the coupling strengths of gravity and electromagnetism are completely arbitrary in this view. In some of these Universes, Electromagnetism could be very strongly coupled in certain schemes meaning that basic chemistry would not arise in some universes. In other Universes the Strong Nuclear force may be too weak to give sufficient binding energy to atomic nuclei, making fusion impossible. In other Universes, Gravity may be coupled far more strongly, creating a Universe of Galaxy Cluster-sized black holes. Other Universes still may be composed of nothing but vacuum energy. Hence we must be living in a Universe suitable for life as we are here observing it, that is the nature of The Anthropic Principle which is used to answer the question, "why is the universe the way it is?" However, the true meaning of the answer comes from Theoretical Physics and M-Theory: The Universe need not be suitable for life, our one just happens to be.

GRAVITATION in HINDI
 
11:32
In this Physics video lecture in Hindi for class 9, 10, 11 and 12 we explained gravitation and force of gravity between two masses. We also discussed on the universal gravitational constant (G). The gravitational force is an attractive force. When two masses m1 and m2 are seperated by a distance r the gravitational force acting between them is equal to G X m1 X m2 / r^2. We talked about why every object we see comes downwards and not upwards. One very interesting fact about gravitation is that if I am attracted by force F due to the earth, it is also being attracted by the same magnitude of force towards me That mean if my mass is 78 kilograms, I am being attracted towards the centre of the earth by force of magnitude 780 newton (roughly, considering the acceleration due to gravity as 10 m/s^2). In turns, this huge Earth is also being attracted by me with the force 780 newton. *********************************************** Click to visit the homepage of our channel : https://www.youtube.com/channel/UCG1-22fo1sIhXGuXYpTRqaA EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.

Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. It is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle. In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens–Fresnel principle. These characteristic behaviors are exhibited when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. Similar effects occur when a light wave travels through a medium with a varying refractive index, or when a sound wave travels through a medium with varying acoustic impedance. Diffraction occurs with all waves, including sound waves, water waves, and electromagnetic waves such as visible light, X-rays and radio waves.

√ Waves and Energy Transfer - World Communicates | Physics-
 
22:45
#iitutor #Physics #WorldCommunicates https://www.iitutor.com The development of our civilisation would have been impossible without effective communication. The early development of speech and later the written word allowed us to evolve a cohesive community that was capable of passing ideas and beliefs from generation to generation. The messenger carrying the information has been supplanted by electromagnetic means of transmission that allow transfer of data at close to the speed of light. To all intents and purposes, the sending and receiving of data over satellite links is instantaneous, limited only by the speed of coding and decoding the information into suitable forms for transmission. Speech and many modern means of communication utilise waves. There are many different kinds of waves. The most obvious form of waves are those upon which we surf. Less obvious are sound waves, and possibly the least obvious are light or electromagnetic waves. In this section we discuss what waves really are, and their importance in the world around us. All waves share one thing in common, they provide a means of transferring energy from one point to another without the physical movement of particles from one point to another. Ocean waves are generated thousands of kilometres out to sea by the action of wind on the surface of the ocean. The energy transferred to the surface of the ocean eventually reaches land a few days later as a breaking wave. However, the water molecules that were originally moved by the wind far out at sea do not move far from their original positions. They pass on their energy to neighbouring molecules, which in turn affect their neighbours. In this way energy is transferred without mass motion. If you put energy into a string or rope by shaking one end up and down, the other end of the string will also begin to move up and down. Energy will have been transferred along the string, but the molecules of the string will not have moved from their original relative positions. In a similar way electromagnetic radiation (which includes light) can be thought of as the transfer of energy from one place to another by varying electrostatic and magnetic fields. If you could take hold of an electron in one corner of the room and shake it up and down, you would find that other electrons at the other side of the room would begin to vibrate a split second later. Energy is transferred from one side of the room to the other by an electromagnetic wave. If particles and molecules don't actually move from one place to another when energy is transferred by a wave, what actually happens to the individual particles? Let's consider what happens if we drop a rock into a pool. Ripples spread out from the position where the rock entered the pool and eventually reach the pool's edge. Floating twigs and straw near the centre of the pool are not washed ashore, instead they begin moving up and down about an equilibrium point. Their vertical motion is a form of simple harmonic motion. This vertical oscillation is transferred outward from one region of the pool to the next. As the oscillation builds up in one area it dies away in the preceding area. The wave is seen to travel out from the pool's centre. Waves travel through the medium carrying energy only: they do not take any part of the medium with them. They cause an oscillation of the particles in the medium as they pass, but every particle returns to its equilibrium position after each complete cycle of the wave. In this way the particles of the medium transmit the wave but do not move along with it, and we can think of the wave as energy moving through the medium. Waves are disturbances that transfer energy from one point in a medium to another point. They may propagate in one, two or three dimensions depending on the type of wave and the medium through which it is moving. The best way to understand how waves are formed and how they travel is to consider a single pulse or wave hump. We can make such a pulse on a horizontal string resting on a table by rapidly flicking one end of the string up then down. As your hand pulls the end of the string up, adjacent pieces of the string feel a force that also accelerates them in a vertical direction. They in turn affect neighbouring pieces of string. As each succeeding piece of string moves upward, the crest of the pulse moves along the string. By now your hand has returned to its starting position and the end of the string has also returned to its original position. As adjacent pieces of string reach the top of their motion they experience a force pulling them back toward their starting positions. The source of the pulse is the motion of your hand, and the pulse is transferred down the string because of cohesive forces (tension) between the particles of the string.

What is GRAVITY WAVE? What does GRAVITY WAVE mean? GRAVITY WAVE meaning, definition & explanation
 
01:52
What is GRAVITY WAVE? What does GRAVITY WAVE mean? GRAVITY WAVE meaning - GRAVITY WAVE definition - GRAVITY WAVE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In fluid dynamics, gravity waves are waves generated in a fluid medium or at the interface between two media when the force of gravity or buoyancy tries to restore equilibrium. An example of such an interface is that between the atmosphere and the ocean, which gives rise to wind waves. A gravity wave results when fluid is displaced from a position of equilibrium. The restoration of the fluid to equilibrium will produce a movement of the fluid back and forth, called a wave orbit. Gravity waves on an air–sea interface of the ocean are called surface gravity waves or surface waves, while gravity waves that are within the body of the water (such as between parts of different densities) are called internal waves. Wind-generated waves on the water surface are examples of gravity waves, as are tsunamis and ocean tides. Wind-generated gravity waves on the free surface of the Earth's ponds, lakes, seas and oceans have a period of between 0.3 and 30 seconds (3 Hz to 0.03 Hz). Shorter waves are also affected by surface tension and are called gravity–capillary waves and (if hardly influenced by gravity) capillary waves. Alternatively, so-called infragravity waves, which are due to subharmonic nonlinear wave interaction with the wind waves, have periods longer than the accompanying wind-generated waves.

Michio Kaku: Are Teleportation, Time Machines & Force Fields Possible with Technology? (2008)
 
38:18
Kaku uses discussion of speculative technologies to introduce topics of fundamental physics to the reader. The topic of invisibility becomes a discussion on why the speed of light is slower in water than in vacuum, that electromagnetism is similar to ripples in a pond, and Kaku discusses newly developed composite materials. The topic of Star Trek "phasers" becomes a lesson on how lasers work and how laser-based research is conducted. The cover of his book depicts a TARDIS, a device used in the British science fiction television show Doctor Who to travel in space and time, in its disguise as a police box, continuously passing through a time loop. With each discussion of science fiction technology topics he also "explains the hurdles to realizing these science fiction concepts as reality". According to Kaku, technological advances that we take for granted today were declared impossible 150 years ago. William Thomson Kelvin (1824–1907), a mathematical physicist and creator of the Kelvin scale said publicly that “heavier than air” flying machines were impossible. “He thought X-rays were a hoax, and that radio had no future.”[4] Likewise, Ernest Rutherford (1871–1937), a physicist who experimentally described the atom, thought the atom bomb was impossible and he compared it to moonshine (a crazy or foolish idea). Televisions, computers, and the Internet would seem incredibly fantastic to the people of the turn of the 20th century. Black holes were considered science fiction and even Einstein showed that black holes could not exist. 19th century science had determined that it was impossible for the earth to be billions of years old. Even in the 1920s and 1930s, Robert Goddard was scoffed at because it was believed that rockets would never be able to go into space.[4] Such advances were considered impossible because the basic laws of physics and science were not understood as well as they would subsequently be. Kaku states that “as a physicist [he] learned that the impossible is often a relative term.” By this definition of "impossible", he poses the question "Is it not plausible to think that we might someday build space ships that can travel distances of light years, or think that we might teleport ourselves from one place to the other?" Each chapter is named by a possible, or improbable, technology of the future. After a look at the development of today's technology, there is discussion as to how this advanced technology might become a reality. Chapters become somewhat more general towards the end of the book. Some of our present day technologies are explained, and then extrapolated into futuristic applications. In the future, current technologies are still recognizable, but in a slightly altered form. For example, when discussing force fields of the future, Dr. Kaku writes about cutting edge laser technology, and newly developed plasma windows. These are two of several technologies, which he sees as required for creating a force field. To create a force field these would be combined in a slightly altered form, such as more precise or more powerful. Furthermore, this discussion on force fields, as well as on the pantheon of highly advanced technologies, remains as true to the original concepts (as in how the public generally imagines advanced technologies) as possible, while remaining practical.[5][6] Kaku concludes his book with a short epilogue detailing the newest frontiers in physics and how there is still much more to be learned about physics and our universe. Kaku writes that since scientists understand the basic laws of physics today they are able to perceive or imagine a basic outline of future technologies that might work. Kaku writes: "Physicists today understand the basic laws [of physics] extending over a staggering forty three orders of magnitude, from the interior of the proton out to the expanding universe."[5] He goes on to say that physicists can discern between future technologies that are merely improbable and those technologies that are truly impossible. He uses a system of Class I, Class II, and Class III to classify these science-fictional future technologies that are believed to be impossible today. Class I Impossibilities are "technologies that are impossible today[when?], but that do not violate the known laws of physics." Kaku speculates that these technologies may become available in some limited form in a century or two. http://en.wikipedia.org/wiki/Physics_of_the_Impossible

Surface tension is the property of liquids by which surface molecules of a liquid try to hold the liquid together by acquiring minimum surface area and acting like a stretched membrane. Inside a drop, each water molecule is pulled with a force by its neighboring molecules. As these forces are equal and opposite, they get neutralized. However, the molecule present at the surface is not attracted outwards. It is attracted only inwards and sideways. Sideways forces get neutralized. But because of the inward force, each surface molecule contracts to form a shape that has the minimum surface area which is a sphere. Therefore, water droplet is spherical in shape.

This video is from our radiography learning website www.radtechbootcamp.com Radtechbootcamp.com was created to help empower radiography students and those preparing for their ARRT exams by providing high-quality videos, quizzes, and mock exams This Video covers the main principles of x-ray production. X-rays are real, and they have to be created in a very specific way. There are three requirements of x-ray production: • A source of electrons • A means of rapidly accelerating (or energizing) those electrons • A means of rapidly decelerating (or de-energizing) those electrons If any of these requirements are missing, x-rays won’t be produced. In radiography, all three steps of x-ray production take place inside of the x-ray tube. • Electrons are produced in the x-ray tube at the cathode filament. • The specific process is called “thermionic emission,” which is the release of electrons in response to heat. A current running through the filament causes it to become extremely hot, so hot that electrons are actually dissociated from the metal and form an electron cloud around the filament. This is kind of like the filament in an incandescent light bulb. A current running through the light filament creates heat which creates light. In an x-ray tube, the filament gets so hot it creates free electrons. A cloud of electrons doesn’t do us much good, so what happens next? That’s where the unicorns come in… not really. • The second step of x-ray production is accelerating these electrons, which gives them extremely high kinetic energy. • This is accomplished by applying an electrical voltage, called the kilovoltage potential (kVp). The kVp creates a strong negative charge in the filament that forces the electrons across the x-ray tube to the positively charge anode. • This makes sense since opposites attract. The electrons are repelled by the negatively charged cathode and attracted to the positively charged anode. The last step in x-ray production is decelerating the electrons. These highly energetic electrons slam into anode of the x-ray tube. • In the process of decelerating, they release their energy as heat and, more importantly, x-rays. The number of x-rays and energy of x-rays are actually controlled by the technologist using the mA and kVp… • Increasing mA (tube current) increases the number of electrons produced in the x-ray tube. Increasing the number electrons increases the number photons. This is the idea intensity. • The effect of changing the kVp is slightly different… • Increasing kVp (tube potential) increases the energy of electrons in the x-ray tube. Increased electron energy results in increased x-ray energy. For more videos like this please visit us at WWW.RADTECHBOOTCAMP.COM

CGI & VFX Tutorials: "thinkingParticles 6 DROP 7: SurfaceForce" - by Cebas Visual Technology
 
24:11
Check out this insightful tutorial "thinkingParticles 6 DROP 7: SurfaceForce" by Edwin Braun of Cebas Visual Technology! SURFACE FORCE OPERATOR Drop 7 This is one of Drop 7 major update feature that deforms and animate a simple 2D plane into 3D particles effects with SurfaceForce Operator. Tutorial by Edwin Braun. Let's dive right into SETUP: Overview SURFACE FORCE: - add the Force dynamic set - pick a standard 2D plane ( parameters adjust as your requirements )+ Wave Modifier (animated phase value). You now see a pre-test of waves running through the object. The waves will affect the particles above it) 1) You can control via the object axis where forces can affect up, etc) 2) using different type of forces 3) the force multiplier ; you can increase the multiplication to 5 or decrease to 1. ( So the forcefield strength will affect the particles as you desire) - intensity (Type of force such as 'pressure' / 'lift' /.... ) - under Show, add Directional force to the setup, and the possible Force Sum. (other selections under Type of force : parallel / tangential / directional / attenuation ) - Attenuation : help control using a standard Alpha gradient so '0' means No Force and 'white area' means Full Force. When you enable Attenuation, you can see the guides that help control how it works, e.g., where you wish the FX to occur and where not to have any effects. NEXT - NEW SCENE SIMULATION DYNAMIC SET U_Deflector - maintain the particles bounding box e.g., if you want particles arranging themselves into a pattern of choice. See that the surface deformation occurring real time on the 2D plane now affects the particles above ! You can modify according to angle of deformation; calculate the vectors and force field vectors. DISPLACEMENT FX - SWIRL NOTE: if we let this simulation carry on, it will eventually gather sufficient speed and dissipate like a gaseous effect. VELOCITY CONSTANT NORMAL CONSTANT PRESSURE CONSTANT WHAT IS SHOW: Show helps you to Visualize as you tweak, how the Force Vector will affect the particles and help predict the effects it will take. You can also adjust Scale, under Attenuation to ‘50’, for example, which makes it parallel to the surface and you will see a rotational movement. You can use this to create GALAXY style effects. FLUID SIMS Throw this in the mix ! With FluidSolver the particles, you gain a BINDING Force for your particles. So the particles are no longer gaseous now but has greater surface tension and acts as a fluid. And you can create all kinds of amazing fluid-like effects and all of it based simply on a 2D bitmap! TURN ON SURFACER : you see the 3D look with the nice fluid ripples. 2D CHECKER MAP Let’s use checker’ and see what we can do. Same deal, go to Gradient Ramp Parameters and control the sharpness of the contour on the plane . Adjust TILING (U.V. Coordinates to 4 or 3 as you wish). Now view the Tiling effect happening on the Checkerboard 2d plane. You get an amazing localised effect! You see little whirlwinds / twisters by changing the 2D texture map with rising particles thru SurfaceForce (remember we used the Parallel combined with Tangential SurfaceForce to create this FX) VOLUMETRIC LOOK To get this, turn on the Surface View and you now see it ! All these fast and east effects straight, controlled simply via 2D texture maps! You can create tons of amazing effects from your library of texture maps /Material Editor. lastly, let's try a CELLULAR TEXTURE MAP (FULL description see post at facebook.com/cebasvt) or email [email protected]) visit http://www.cebas.com Watch More CGI & VFX Tutorials HERE ►https://bit.ly/2OBEnDY WANT TO GET FEATURED?
