​@@elio7610 should be, but i'm wondering about the corners which light could possibly go through in a shorter time frame, causing weird distortions not to mention light bouncing off of materials and all of that, making the sight a blur

@@elio7610 Probably 🤔.

mindblowing!

A literal window to the past 🪟.

Exactly my feeling. The problem is, you can visualize the behaviour only for a very tiny section of the whol thing (1 wave cross section + 1 electron). The real process in 3 dimensions and for multiple elctrons and waves is overwhelmingly more complex. I can't imagine anything of this tbh.

I picture this as like the light gets pushed backwards a bit when it comes across a medium, and then it continues to move at c. But because it got pushed back when it touched the medium, it'll reach the other side a bit late even though it's still moving at c. So from our perspective, light seems to be slowing when in fact it just got offset backwards a bit.

Yes 😅. Also; the constant, called: ”the speed of light”, is actually just the speed of light, in a vacuum.

@@PC_Simo It's actually not the speed of light that is the constant. The actual constant is the speed of causality=C. This is the speed of how fast a change can occur. Light itself could be infinite in speed, but is limited by the speed of causality.

3Blue1Brown indeed has some good animations on it (KTzGBJPuJwM & aXRTczANuIs). I also like FloatHeadPhysics (JZOn1B8K8mA) although the "pull back" animation isn't that good - it has some really interesting comments though. I don't like the FermiLab version as it does not really explain it properly (well at least as you can say "properly" as of course it's far more complex in real life than any of those videos imply).

Someone explain to me how this works as a photon of light. Whenever I see videos or explanations done about this, everyone starts showing waves. While I know light behaves both as a wave and as a particle, if we don't know how an individual photon 'knows' it transitioned into a different medium, there's a possibility this wave theory is also incorrect. Also, the way it's explained here and everywhere else is that a single atom's electrons changes the wave and then it gets passed on to the next atom's electrons.... but isn't this additive? If that were the case, enough length of the material would make it completely opaque, and well before that the refractive index would be observed as being dynamic. It makes 0 sense that this is considered the proper explanation.

That stuff happens a lot to me too.

you being spied on by your phone and any mic on laptop

Google heard you then forced action lab to make the video

I mean, as long as it has speed it can slow down.

That is just a normal thing, no need to freak out. Tons of information fly through our head everyday but we never give them a damn. When you focus on one topic, you'll pay attention to information of it, if it fly through your day again. And then you just think "Wait, does universe listen to me?"

Wait- holy hell this just gave me actual virtigo. This explanation means that in the truest sense of the word, no mateiral is transparant, it's simply a material that has an electromagnetic-wave-propagation effect. 'Air' would be a good case study becuase I'm uncertain if it has enough density to compare to something like Water or Acrylic... but except in a true vacuum, you will never receive the electron that the originating atom created... And in low density fluids... how deeply could an EM wave penetrate before it MUST hit another atom to propagate and potentially delay? Your eyes are constantly re-propagating EM waves so for that matter... *head asplode*

Methinks this question has the wrong direction. It e.g. does not explain why vacuum is perfectly transparent. And it gets difficult to explain why water is transparent and snow is not. The question is why some material is not transparent.

@@bosslca9630 A vacuum, and gases in general, will be transparent because the photons can actually pass through without interacting with anything. Gases are mostly empty space, part of the reason their densities at normal pressure are so low compared t liquids and solids where the atoms do contact each other. There is some atomic interaction between light and gases - that interaction is why the sky is blue for example.

@@peglor Compared to vacuum, air is incredibly dense. It is as dense as it can be without increasing the temperature in its space. It is so dense it will knock you over if it travels as 20m/s. "Speed of light" in materials is indeed a conundrum that very likely proves we don't understand what light is. It is neither hardness, element or state deciding if a material is transparent. Coal is the perfect light stopper, unless you compress is insanely hard. Crude oil is also blocking almost all light, until you increase the mass of the molecules and turn it into plastic. No metal is ever transparent, unless you "fix" it in a ceramic grid. The reason light "slows" down in different materials is probably because it never travels through it. It's only the waves going through. Sort of like sound through a wall.

Thenproblem is that youbare thinking in particles, everything is transparent and opaque, it depende on the wavelenght, the window of your microwave oven is opaque to microwaves but transparent to visible waves.

these preprint papers claimed reversing entropy. What do you think about this? Experimental Demonstration of Energy Harvesting by Maxwell's Demon Device And An Autonomous Mechanical Maxwell's Demon

you can do this w one photon, but the absorbed an remitted is very misleading. The photon remains coherent , which wouldn't work if it were absorbed and remitted classically..but then it gets into more semantics of coherent vs incoherent scattering. The juice is not worth the squeeze,

🚩This is why many people have started hating scientists 🤢🤢🤮They lie & manipulate with ZERO shame🤢🤢🤮 Light NEVER slows😡It just scatters in denser material, which makes it takes longer time to pass through🤏

A very small portion of the photons actually are being absorbed and re-emitted, it's just that the majority are making it through and just being interfered with over and over again. In other mediums, the ratio is different, and so transparent-ish things can take on colors.

No please forget about this idea. It's completely wrong and bogus. Just think about one thing: Why would the re-emitted photon fly in the direction it needs to fly and not in any other random direction?

Oh no, he might need to use his vacuum chamber, and he never uses it😊

A wave decrease in amplitude when it loses energy, not frequency. On a microscopic scale, the release of energy takes place in the form of quanta, which are released in their entirety. At least that's what quantum physic says. Yes, there might be a wave going through glass without slowing down, but only at the beginning, until the transient regime passes.

Or lenses?

Optical Computing is a field of ongoing research, and there is a lot of fascinating work being done in building logic mechanisms using light’s properties. Typically these techniques leverage quantum effects such as wave interference and polarization - check out Huygens Optics channel

If only it were that easy. Photonic logic is the use of photons (light) in logic gates (NOT, AND, OR, NAND, NOR, XOR, XNOR). Switching is obtained using nonlinear optical effects when two or more signals are combined. Resonators are especially useful in photonic logic, since they allow a build-up of energy from constructive interference, thus enhancing optical nonlinear effects. Other approaches that have been investigated include photonic logic at a molecular level, using photoluminescent chemicals. In a demonstration, Witlicki et al. performed logical operations using molecules and SERS. The basic idea is to delay light (or any other signal) in order to perform useful computations. Of interest would be to solve NP-complete problems as those are difficult problems for the conventional computers. There are two basic properties of light that are actually used in this approach: The light can be delayed by passing it through an optical fiber of a certain length. The light can be split into multiple (sub)rays. This property is also essential because we can evaluate multiple solutions in the same time. When solving a problem with time-delays the following steps must be followed: The first step is to create a graph-like structure made from optical cables and splitters. Each graph has a start node and a destination node. The light enters through the start node and traverses the graph until it reaches the destination. It is delayed when passing through arcs and divided inside nodes. The light is marked when passing through an arc or through a node so that we can easily identify that fact at the destination node. At the destination node we will wait for a signal (fluctuation in the intensity of the signal) which arrives at a particular moment(s) in time. If there is no signal arriving at that moment, it means that we have no solution for our problem. Otherwise the problem has a solution. Fluctuations can be read with a photodetector and an oscilloscope. The first problem attacked in this way was the Hamiltonian path problem. The simplest one is the subset sum problem. An optical device solving an instance with four numbers {a1, a2, a3, a4}. The light will enter in Start node. It will be divided into two (sub)rays of smaller intensity. These two rays will arrive into the second node at moments a1 and 0. Each of them will be divided into two subrays which will arrive in the third node at moments 0, a1, a2 and a1 + a2. These represents the all subsets of the set {a1, a2}. We expect fluctuations in the intensity of the signal at no more than four different moments. In the destination node we expect fluctuations at no more than 16 different moments (which are all the subsets of the given). If we have a fluctuation in the target moment B, it means that we have a solution of the problem, otherwise there is no subset whose sum of elements equals B. For the practical implementation we cannot have zero-length cables, thus all cables are increased with a small (fixed for all) value k'. In this case the solution is expected at moment B+n×k.

Isnt that great science wize. Mostly swiped from wikipedia or so.

The radiative pressure of the sun's photons forcing through the dense core (1.622 x 10 to the 5 kg/m3) and the surrounding currently created elements as well as those present in the initial molecular cloud does slow the straight pathway of a lot of the photons. This is what holds the rest of the gases in place as the density decreases. Eventually these photons WILL leave the sun and reach us, about 200,000 years after their creation.

You can think that. It isn't right though. The problem with analogy is we are the quantum scale and our intuition is all wrong. None of these things are objects as we understand them and the concept of a medium is meaningless.

@@101Mant Yep and i did say that. But to wrap your head around the phenomenon in a practically usable way, it does help to look at it in simpler terms.
