[@TerryProthero]

I've seen physicists talking about light slowing down when going through a transparent material. Apparently, what's happening is more complicated than atoms absorbing and emitting photons. It has more to do with light acting as a wave through the material and interference with that wave. It might be more accurate to imagine it as the electrons in the material causing drag on the photons. Like a piece of metal moving past a magnet. Although I'm sure some physicist will have a problem with that explanation as well. I'm probably not describing the process exactly right, but I think it's closer to what is actually going on.

[@DFPercush]

Had to pause the video to find this comment lol. As an armchair physicist, basically yes, the resulting light in the medium is the original incoming photon plus all the electrons being disturbed by, and affecting as a result, the electric field. That all adds up to one composite wave which has a sub-light group speed. Interestingly, the phase speed can be faster than c, that's why you sometimes see articles about a material having faster-than-light properties. But the phase speed doesn't carry any information and doesn't represent the speed of the actual photon.

[@MCMaterac]

@@DFPercush Haha, I did the same. The absorbed photon loses it's momentum, doesn't it? Why would it keep its direction when reemited? It's bad how many people repeat the myths explaining the refraction, so it's nice to see the comments of You two. Here's a video I found when searching for the answer and that I enjoyed: kzbin.info/www/bejne/eYbNpWZsiKlmnpo The part that follows (@6:18) makes some sense, but is also wrong. Seems the author went with the Fermat principle. Discussed in the follow up video to the one I've posted above: kzbin.info/www/bejne/hH3QoYGDZdiaj80

[@Doriedejai]

So if there was a specific frequency wave pattern to affect the direction of light(photons), would that make it possible to have physically touchable light? Or possible to manipulate a collective bunch of photons together as a hologram? (Still learning, if I sound off correct me please lol)

[@thewanderingmistnull2451]

@@Doriedejai I assume you mean solid light, since all light is physically touchable. And to answer that, I don't think so. No frequency of waves in water or air makes them solid enough to press without passing through.

Mr Lab : *THE CREATION OF LIGHTBENDERS*

[@baerdred]

Just for completeness, I'd like to mention that due to diffraction (caused by light being both a wave and a particle) light actually IS capable of moving around corners and not only in a straight line, even without using this material. However, the amount of light that "bends" this way in a normal environment is very minimal, so the effect is not generally noticeable.

[@black_crest]

Is that why I can see the lensing effect when I look at an object far away through the edge of an object that is just after my eyes?

[@baerdred]

@@black_crest I'm not sure what you mean by lensing effect, since diffraction from an edge shouldn't change the focus noticeably, though it might warp the image you see. But it sounds to me like you are describing a diffractive effect.

[@Fuzzy1528]

AAH SO MANY PEOPLE THAT UNDERSTAND THIS

[@petep.2092]

@@black_crest Possibly. The lensing effect caused by edge diffraction is not discernible from the lensing effect caused by refraction due to materials with different refractive indices. Radio waves also bend when passing over a sharp edge. Light also bends due to gravity. The bend is not negligible when large distances are involved… scientists have measured the shift in apparent position of stars due to our sun (seen during a solar eclipse) and during the Cold War, India and Russia maintained a radio communication link by aiming a radio wave at the sharp peaks of the Himalayan Mountain range that ordinarily blocked line of sight radio communications and made the laying of copper/fiber cable impractical. The knife edge peaks of the tall mountains gave a signal path similar to a radio wave bounced off the ionosphere, but was not subject to the varying and unreliable height of the ionosphere.

This is why a high power laser beam, one intense enough to heat the air as it passes through, will bend upwind into the cooler more dense air. The wind has to be very low speed - 4 mph of less - for this effect to happen. I have seen it personally with a 100 kW CO2 laser and may be the first one to ever capture it on video. This was in about 1972 at the Kirtland AFB Sandia Optical Range. The laser was a CW gas dynamic laser.

You are also sending the light just above it's critical angle for those materials(form sugar to water). At critical angle the light goes straight with the boundary between two materials(here sugar and water).But if the angle of incidence is larger than critical angle then the light doesn't go to the material which have lower refractive index(here water),totally comes back to the material which have much refractive index.This phenomenon is called Total Internal Refraction.

so something flat looks curved because of a difference in density of the medium in which the light is traveling through. So if the earth was flat, would the difference in air density affect the light traveling through the air making us see curvature?

Cool experiments! Near the end of your video, you showed a picture of a mirage, due to a temperature inversion. Well! There's another property of temperature inversions that I've only seen once outdoors. At U of I in Champaign-Urbana I loved to take long bike rides in the flat country. It was hot, and sunny but there was no breeze. I looked to the side and the soybean plants were being blown by a strong wind in a circular pattern. There was a powerful vortex (a "dust devil"). Dust and dry leaves were being sucked upwards for more than 500 to 800 feet. I understand the basic idea of a vortex; somehow .the hot air at the ground punctured through the layer of air and began spinning, but I never saw a stationary dust devil before; it didn't move at all during the half hour I watched. This might be put to a practical use if a dark cone was built, with hot air being drawn through ducts to a central column with a wind turbine generator at the top

[@PeterMilanovski]

Gravity has nothing to do with it! If it were the case, then you would see the same effect while shining your torch out into the distance, or the lasers that are used by telescopes to point out into space would never point where you want it to if it was pointed somewhere at less than a right angle to the earth... It's what I would call an atmosphere! Be it water and sugar or gasses on a planet or even a star but the people in astronomy like to call that effect gravitational lensing which is misleading because it's not gravity that's doing it..

[@BillPalmer]

@@PeterMilanovski oh, you would notice if your flashlight beam deflected a micron over a mile , would you? How much atmosphere extends beyond the boundaries of a galaxy?

[@PeterMilanovski]

@@BillPalmer no I wouldn't, not so much with a torch, it was just a basic or bad example, but a laser on the other hand is what I should have said! While you would not be able to see it from the point of view of the laser holder but at a distance from space and if the beam was wide enough to be visible, as the beam of light travels along the ground from its point source, eventually the ground will fall away as it curves around and the light beam then begins to cross through the different layers of gas in our atmosphere and this is where the light beam should bend! If gravity played a part in it, it should curve around with the earth possibly even forming a complete circle but since gravity doesn't affect light, it has to be something else, the only thing left is the atmosphere! There's nothing else! Regarding the atmosphere boundary of a galaxy, I don't think anyone really knows! That's like asking where's the boundary to our solar system? Sure, two of our probes have gone through something that could be a boundary but as far as I'm aware no one has ever seen it and there's plenty people looking out into space all the time!

[@FuneFox]

@@PeterMilanovski something moving at the speed of light or near it would not be able to orbit the earth and actually it would barely even be affected due to its speed, light speed is 670,616,629MPH while the speed an object needs to escape earth's gravity is 25,020 so the effect earth's gravity would have on light is too small to see or directly measure without better than NASA grade equipment. its like saying that a marble will fall to the center of the earth because of the gravity. you are overestimating the power of earth's gravity and also please could you explain what causes that light distortion around black holes if not gravity?

*LIGHT DOES NOT MOVE AT THE SPEED OF LIGHT (in a vacuum) BETWEEN ATOMS IN A TRANSPARENT MATERIAL!* (For normal transparent materials with a real refractive index >1, such as Quartz crystals, Soda-Lime window glass, water, many plastics, etc.) Please don't spread incorrect explanations just because they are easy to understand, or sound nice. Light uniformly moves at a lower speed through transparent materials with refractive indices > 1. It doesn't get absorbed and re-emitted after any significant amount of time and, even if it did, the excited atoms would radiate the light uniformly in random directions (just like fluorescent and phosphorescent materials radiate light in all directions, even when excited by a very directional laser, because these materials actually do absorb the incoming light and re-radiate after some time has passed). Light also doesn't keep moving at the speed of light in a vacuum, while it travels in the space between atoms (for transparent materials with a real refractive index > 1). It moves with exactly the same momentum vector once inside the transparent material, irrespective of when it gets close to an atom. This is the same physics which enable long-wavelength infrared waves to pass through dust clouds when the dust particles are smaller than the wavelength in question, whilst shorter wavelength light can get scattered. Similarly, visible light has a wavelength which is THOUSANDS of times longer than the dimensions of even the largest atoms, so it simply passes right on through without being deflected or having the ability to 'bounce' off of the atom (as long as the atom doesn't have an electronic quantum transition with a characteristic energy which matches the photonic energy of the light). To be clear, when traveling through a transparent material, the light which makes it through to the other side in a straight line, does *NOT* get "absorbed and re-emitted" by atoms. Any wavelengths that are absorbable by the atoms which make up the transparent material in question, will either be lost completely (after absorption, the excited atoms usually either vibrationally relax to their ground state, or give off a lower energy photon with one or more radiationless vibrational transitions inbetween, with the difference in momentum being transferred to the crystal lattice via phoNONs).

[@grahamcustard7716]

I wouldn't be too quick to criticise his description of light transmission. Light is 'reflected' by a mirror in exactly the same manner as described in the video. At the atomic level, light is absorbed and re-transmitted at the same angle, but also in the same direction of propagation. It does not 'spread out in random directions' upon being re-emitted. The only time that this randomness appears to occur is when the reflecting surface is a jumble of atoms, as on a sheet of white paper. Similarly for light transmission, the light travelling through the medium is absorbed and re-emitted in the direction of propagation only, with minimal or no emission in other directions. But let's be honest here - no one person fully understands how light is propagated as it appears to exhibit features of waves and particles, but the absorption and re-emission principle is about as close to the truth as we can get with our current understanding of physics.

[@ItsLadyJadey]

Too long, didn't read.

[@mortlet5180]

Graham Custard ; You said "no one person fully understands how light is propagated" and that "the absorption and re-emission principle is about as close to the truth as we can get with our current understanding of physics". First-off, it is very important that you know I am not trying to discredit, belittle or insult you in any way, so please read the following as it's intended: a logical discussion where I try to gauge how much someone knows and what their biggest gap in knowledge or mis-understanding is, over a brief KZbin comment thread. That said, those two quotes did indicate that you are unaware of developments in the physics of electromagnetism, past the 1920's or so. This was the period of the "first Quantum revolution", where wave-particle duality (forced upon Physics by Boltzmann's introduction of energy quantization to resolve the "Ultraviolet Catastrophe", together with Einstein's discovery of the photoelectric effect, which proved that the Electromagnetic field itself was quantized) became a frustrating complication in understanding the interaction of light with matter. Before this time, Young's double slit experiment seemed to conclusively show that light was an electromagnetic wave. This meant there were no photons which could directly interact with atoms, rather light was a continuous wave, which could (in principle at least) spread out infinitely far from it's source. Thus the spherically spreading wavefront would become larger and larger, while the waves themselves would become ever smaller and smaller 'ripples' as they travelled (as per the inverse square law). If you placed some objects in its path, each one would still be able to absorb a small amount of energy from the wave, only blocking the wave from spreading directly behind it, but not affecting the wave at the other side of its arbitrarily big sphere of influence. In this case, reflection is also simply a special case of refraction. This is why you can make dielectric mirrors reflect light by simply depositing transparent layers of different refractive indices, without any metallic or opaque substance being required at all. In fact, even regular 'transparent' glass can become a perfect reflector, as long as you keep the angle at which the light strikes the glass smaller than the critical angle (which is what happens during Total Internal Reflection). In the case of light reflecting off of a very reflective metallic mirror, the absolute value of the metal's refractive index (which is in general a complex number) is just much lower than 1 (yes this can indeed result in the *phase* velocity of light being faster than that of light in a vacuum). In none of these cases is the light wave required to be either partially or wholly "absorbed and re-emitted". So what happens when light DOES get absorbed in this pre-quantum (usually referred to as 'classical') world? Well, either the energy absorbed from the wave gets converted into heat (which leads you down the road to the Ultraviolet Catastrophe), or at least some of it gets re-emitted as light of a different colour (longer wavelength). If the light gets re-emitted practically instantaneously after absorption, it is called fluorescence; if it takes seconds to hours before re-emission occurs, it is called phosphorescence. But in *ALL* cases where light energy is absorbed, any subsequent re-emitted light is as a diffuse glow (which is why you don't get a 'reflected' yellow laser beam if you shoot a blue laser at a yellow fluorescent or phosphorescent coating (similarly, laser pumped dye-lasers still need to provide a proper gain cavity for the emitted fluorescent light to 'build-up' into a single coherent wave. This post has gotten so long that typing any further is becoming buggy so I will continue my response in a second post after this one. End of part 1/3.

I've been thinking about a solar panel that doesn't only gets direct sun light, but also an extra bump by bending the light in the surroundings. So that way more photons get to hit the panels, reducing the area needed to create the same amount of current. Would that be possible?

[@petep.2092]

Yes, but concentrating the light by using a lens or mirror will also concentrate the heat from the sun -which comes in the form of infrared light and is also refracted and reflected-on to the solar panel, which could raise its temperature to the destruction point. Higher temperature will also result in higher ohmic resistance, which will result in higher electrical loss, negating some of the benefit of concentrating the light. I'm not sure, but there may be a limit on how much electrical power you can get out of a solar panel depending on its materials, construction, etc., i.e. increasing the light more and more may not continue to give more and more electrical power.
