Why is it that, when light travels in a medium, we say it's made of "quasiparticles"?
I get why, in this model, light isn't really "made of" photons, because photons, by definition have zero mass and travel at $c$, whereas these quasiparticles, if I understand correctly, do ...

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 ...

Photon explanation of dielectric effects?
When an electromagnetic wave passes through a medium, the electric component of the wave will induce a dipole. I believe this can happen in a number of different ways, including rotating of a polar ...

Photons when passing through matter
I am wondering whether there is a simple—or complicated—way to explain from a purely quantum mechanics (or QFT) viewpoint what happens to the photons when they go through some material whose index of ...

How can my window not scramble the image of my yard?
How can an image pass through a window if the atoms in the glass randomly emit photons in any direction?
I've read that glass is transparent because the atoms don't readily adsorb visible light, so 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 ...
