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,...

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?

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 do I use a sunstone? How does it work?
I have acquired two pieces of Icelandic Spar (optical calcite) with surface and internal fractures that should be serviceable as sunstones.
I have observed the double refraction and cancelling double ...

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 ...

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 ...

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?

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 ...

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 ...

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 ...
