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 ...

Why does the soap bubble shine with the colours of the rainbow?
Is it because of
refraction of light in water?
a mixture of UV rays in sunlight?
polarization of reflected light?
interference of light reflected from external and internal
film surface?
or maybe ...

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?

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 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 ...
