How does Dipole coupling affect macroscopic polarizability and refractive index

I have taken some measurements of refractive index (refractometer (commercial Brix meter), nD20 i.e. 20 degrees C and 589 nm) and density of sucrose/water mixtures and also of ethanol/water mixtures. ...

Why exactly does light bend when it enters a different medium? [duplicate]

Simply: what happens to the electric(and magnetic) fields when it enters the medium? How does it interact with the molecules and how this interaction leads to the bending of light?

A Question About Brewster's Law

In most textbooks I read, they state that when the angle of reflection + angle of refraction = 90, there is maximum polarization. What I don't understand is what maximum polarization means. Does it ...

Why does light not polarise off metallic surface?

I am aware that light partially polarizes upon reflection off a non-metallic surface, however, why is it that this only occurs for non-metallic surfaces?

Brewster Angle - what is the polarization state of the transmitted wave?

When unpolarized light is incident at Brewster's angle, what I understand is that the reflected wave is S-polarized. What is the polarization state of the transmitted (refracted) part of the wave?
