Double refraction in Calcite Crystal
In the above text it is mentioned that the incident light ray travels along the principal section.But any ray which travels along the principal axis should not go through the double refraction. Then ...

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.
...

If the Brewster's angle is considered to happen with no reflection, then how is the refraction angle considered to be 90°?
So basically my questions are these:
Is the refraction angle always 90 in relation to Brewster's angle?
And if the refraction angle is the angle between the reflected ray and the ray that passed the ...

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 ...

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?

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 ...

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 ...

Will the refractive index of a electrolyte change when chemical reaction happens?
Since polarization is the reason of refraction, then anything that changes the structure of molecule, atom, or electron will present as a change of reflection. Thus, to my understanding, chemical ...

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 ...

What happens to the photon when a polariton forms?
When a photon passes from the vacuum to a medium such as water, a polariton forms in the water which carries the energy from the photon at a slower speed through the medium. The polariton being ...

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?

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 ...
