Is there a good quantum explanation of refraction? [duplicate]
I'm aware of the classical explanation of refraction which deals with light being a wave that gets "slowed" down while passing from a medium to another. One problem that I have with this ...

Why the photons are deflected during the refraction? [duplicate]
From what I learnt, when photons are passing throw a denser environnement with an positive angle (from the atmosphere to water for exemple), they are slow down. But I can't understand how this ...

Why can't two truly identical experiments on quantum scale give the same result?
When we refract light on air/water interface, some part of light is reflected while some of it gets refracted.
My question is when we consider light as a photon and send it (photons) one by one, what ...

Do photons “bounce off” of electrons?
I’ve been reading a book, and in one part the author explains how electrons only absorb the wavelengths of light that can take them to an excited state, i.e. that can take the electrons to a higher ...

Acceleration of photon
When light moves from one medium to another its speed changes due to the refractive index of the medium and so does its momentum given by $h/λ$. What is the acceleration of photon when it makes ...

Does a photon also come to rest after some time while travelling through a medium?
If you fire a bullet in air, after some time it comes to rest because of air resistance forces. But what about photons? If they are also particles, then the same thing should happen with them. It ...

How can we explain, from quantum mechanics, why do we see light rays bend when light goes from one medium to another? [duplicate]
Refraction: I want a qualitative Quantum Mechanical explanation of why do we see light rays -in the classical picture- bend when light goes from one medium to another. I read that it is due to ...

How is light slowing down in a medium thought of in the photon picture? [duplicate]
The speed of light in any medium besides vacuum is smaller than $c$. In a classical way, I just look at that as a wave that propagates less fast, the change in EM-field is passed on slower. How should ...
