The density gradient of the atmosphere does this too, allowing you to see objects that are geometrically below the horizon, and causing sunrises to appear earlier and sunsets later than they occur astronomically. The dispersion in this bending (variability with wavelength) also causes the "green flash" occasionally seen just at sunset over the ocean.

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.

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.

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.

On those beautiful sunny days the light coming from the Alps is bent in a way which makes them appear very near and really huge.

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

I've also seen mirage that have two different transients from the surface, making ships look flipped upside down and other weird appearances. Mirages are cool.

I am 32 years old and I finally got an explanation of how mirages are created! Thank you! 🙌🏼 I love your videos!

the first example of me seeing this phenomenon is when I saw right on top of car roof on a hot day, and the heat bends whatever is supposed to be above the roof from my perspective, that looks like a smoke like silhouette, pretty cool

Ive actually learnt more watching your videos than i ever did in school! Keep up the great work!

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. Based on this concept optical fibers are made.

I'm a photographer and designer and have been dreaming of ways we can incorporate and take advantage of these physics in light emitting and light gathering equipment. In a way the lenses already do use a few of these methods but I think there are some gases or fluids we could manipulate in a way that allows us to effectively control the shape of it as a lens element.

Really awesome experiments and explanations. About the mirage: I knew that it has something todo with the hot air above the road. But I thought it is a "reflection" (straight in, straight out), I didn't know that the light was "bent" (or is this basically the same?). So maybe you can do a follow up about "reflections"? Additionally: sunglasses with polarisation filters can filter away mirages, so what exactly causes the light from the mirage to be polarised? Thank you 🙂

12:34 I used to always wonder why on hot days it looked like there was water on the road but as I got close it went away

After the video. My brain was like. Ahhhhhhhhhhhhhhhhhhhhhhhhhh What!

Put a pencil in a glass of water and see what it looks like. It should look bigger because the light is being bended as it goes through the water

Great video! I found myself unconsciously leaning forward towards my monitor and dropping my jaw! I'm going to be thinking about this for years

@The Action Lab Great show. Thank you. Did you have sugar water mixed when you was using the Lazer and demonstrating how light bends down at the bottom.? How much was your mixture ratio.? Thank you.

Is it possible to replicate this effect using a sphere? (Made of glass, epoxy or something else). For example with epoxy, could it be made more apparent by using transparent acrylic in between alternate layers of spherical epoxy to increase refraction steps?

yes, l want the easiest right answer :) loved it! Great video and very interesting!

You dont need science classes when you subscribe to "The Action Lab" *Less experiment more science class*

Love these experiments. One question: In the sugar water box, why does the light bend down? Why can't it bend up? Does increased density always influence light this way? I guess in a way GRAVITY has bent the light in the sugar water. Without gravity the sugar would not concentrate at the bottom. Interesting to think on it. Thanks

An example of bending light that you didn't mention and it doesn't seem to have been mentioned here in the comments is optical fibers. Though the original fiber optic strands worked by a sharp change in the refraction index in between the two types of glass that made the fiber, which produced a total reflection like in a mirror, the most modern ones use a single type of glass diffused with dopants to change its refraction index gradually so that the light is bend towards the center of the fiber instead of reflected on its walls. It is a better solution because with the old fibers, the paths taken by light going straight through the center and that bouncing at angles on the interior walls was widely different. This meant that the pulses of light, the ones and zeros, got spread over the length of the fiber as the leading and trailing edges of the light pulses reach the other end at different times depending on the path they took. On the current fibers, the light tends to get more focused towards the center path instead of getting continuously bounced about.

So can you make an invisibility cloak by creating an air density gradient around you?

@A68AGaming

Yes, but it would be harder than you think. Plus you would need a material that bends it how you want it, so you are invisible. Meaning you wouldn't be ivisible from some angles

You'll have to leave your eyes visible and opaque unless you want to be blind.

The fact that we having to explain basic concept to adults is truly amazing.

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.

I have no understanding. Fill me in.

Just a quick question on this but if the camera were to be pointed directly at the laser source when the light is being curved down would we see a glow or just what is above the laser? Would everything be shifted down but still visible?

I read somewhere that this effect with cold lake water and warm air layer was able to bend light as telescope lens does, and sometimes allows people to see the opposite coast of the great lakes like they're right there, even though they're hundreds of miles away.

It's called looming. Even without temperature differences, looming in the atmosphere is always present because of the atmospheric density gradient due to gravity.

Thanks a lot for this cool video! Love it! One question: reg comment af 6:14 “light takes least time between two points”. I heard this explanation but find it hard to believe, because how does light know when it leaves that it will hit a material with higher density?! Do you have an alternative way of looking at this? - thanks! :)

I think he confused cause with effect. The light doesn't bend because it wants to travel the shortest time. The light bends because of some other phenomenon, but we can use the geometrical crutch he presented to calculate it's path. Also, his geometrical crutch only works if P and Q are at the same distance from the plane connecting material n1 and n2.

Hello. Very interesting video!. I am wondering if there is a mathematical formulation that allows computing the bending of a light beam travelling through a material, assuming that the variation of material density is known in every point. Does anyone know?

Hi, could you please put a link to the video you mentioned within this video of how you turned a reflector by using light. Thank you.
