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?

Double refraction in quarter wave plate and nicol prism
I have read in one of the textbook (local author) that when an unpolarized light is passed through nicol prism (parallel to the long sides of principle section),the light ray splits into two namely ...

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?

What happens if polarized light passes through calcite or some other birefringent material?
every explanation of birefringence I find talks about unpolarized light entering Calcite, but what if I use a polarized light? Will that mean that as I rotate the crystal the light will disappear then ...

Polarized light in single mode fiber
In single mode fiber the light propagates in two orthogonal planes. Input will be linearly polarized light, which state of polarization will be on output and why? And if there will be some different ...

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 ...

What polarizes a rainbow?
What polarizes the light from a rainbow. I already did some search and couldn't get a clear answer. All I could find was the light is polarized on the direction light is entering. What happens to the ...

Polarization in Nicol prism
My book reads
"When unpolarized light is incident on nicol prism (made of 2 crystals joined by Canada balsam a type of glue) it divides into 2 rays, both rays are plane polarized and electric field ...

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 ...
