Question about slowdown of the speed of light in solid medium

In summary, the conversation discusses the concept of light being slowed down in a material due to its interaction with the lattice ions. The explanation given is that the photon is not absorbed but rather re-emitted with a slight delay, and it may encounter other ions as it travels through the material. However, this explanation is not entirely accurate as a single photon interacts with thousands of molecules at the same time. The correct explanation involves the collective phenomenon of phonon modes in the lattice.

Doesn't anybody on this thread have an EM textbook?

No I don't. I have several. Now what's your point?

So what happens to the original photon after the interaction ?

Yes, what happens to the original photon after the interaction?

Is there any analogy between the way that the phonon mass behavior of atoms in a transparent solid transmits light and the way a metal conducts electrical current?

Not exactly, because there is no "carrier" for optical transport in solids, where as there is one for electrical transport. One can typically use a Boltzmann transport equation to describe charge and even heat transport, whereas I don't recall the same thing being used for optical transport.

Does the photon still exists?

Physicsissuef, the way that you keep making posts that add nothing new but reiterate your previous questions give the appearance of self-centeredly clamoring for attention. I'm not saying that you're necessarily being childish, just that this approach may actually discourage people from answering you.

I think my questions are very simplified, so everyone can understand. So my question was, what happens with the light after the interaction with the surface?

Nobody knows ?

Read the section on index of refraction.

I have. Can you tell me how E&M phenomenology explains why carbon atoms arranged in different configuration can give different index of refraction? I've gone through Jackson, and he certainly says nothing about it.

And if you somehow forgotten why this is relevant, note that you took exception to the info quoted from the FAQ, in which I had tried to explain why "photons" moving through a medium interact with the structure of the material, and why the active phonon modes of the material dictates the nature of the optical transport in that material.
