What is an example of experimental confirmation of Fresnel equations?
I have been reading about Fresnel equations, but I am struggling to find a single experiment where it was experimentally demonstrated that indeed polarised light follows the function predicted by ...

Polarization by reflection - Brewster's angle
When incident light hits an interface of a dielectric surface at the Brewster angle, I understand that it will result in the generation of a perfectly polarized(horizontally) reflective ray and a ...

Polarization of light and Brewster's angle in internal reflection
In almost all sources I read so far, Brewster's angle is defined for light incident on an optically denser medium from an optically rarer medium. Is the concept of Brewster's angle applicable when ...

What causes the circular polarization of light from outside Snell's window?
Wikipedia and other sources claim that the internal reflection underwater outside Snell's window is circularly polarized. What is the mechanism that causes this circular polarization?

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?

Is true black possible?
Black is the absence of light because it absorbs light, but when we create black paint or black objects, light is always reflected, either in all directions in matte or smoothly in shiny black objects,...

What causes these rainbow effects using a polarizing filter on an airplane?
I know that light reflected from a surface at 45° is polarized and that for a similar reason skylight arriving from a direction orthogonal to the sun is polarized too.
Photographers make use of this ...

How does one show specific thickness and wavelength determine full transmission of electromagnetic waves?
How does one show that thickness and wavelength determine the full transmission between two different dielectric media if the boundary condition equations between two dielectric media are independent ...

What are the properties of the partially polarized light on refraction?
When a ray of ordinary light is passed on the water's surface, the reflected light will be completely polarized (vibrations in one plane).
My question is what will be the plane of vibration in the ...
