Ray separation in waveplates
In a birefringent medium, the ordinary and extraordinary rays have different Pointing-vector directions and, therefore, different propagation directions, since the direction of the Poyting-vector ...

What can be the possible causes for variation in stress-induced birefringence in an isotropic material?
Birefringence is the phenomenon of a material having a refractive index that depends on the polarization and propagation direction of light. When an unpolarized light passes through such a material, ...

How in Faraday rotator, changing magnetic field will change the refractive index of RCP and LCP?
Can anyone mathematically prove how in the faraday rotator, when we change the magnetic field direction, it will change the refractive index of Right circularly polarized (RCP) and Left circularly ...

Why is Nicol prism cut at 68 degrees specifically?
Why not just some other angle but this specific one? Does it help in some way to polarize the ray?
I have tried searching everywhere, but they only show that the crystal is cut at an angle of 68 ...

Torque on Quarter-Wave Plate
When circularly polarized light is passed through a quarter-wave plate, the plate experiences a torque. I understand this is true because angular momentum must be conserved, but I don't understand ...

What does the refractive index for e.g. alpha mean?
When I look for some materials like https://en.wikipedia.org/wiki/Barium_sulfate and want to extract the refractive index then there is written: (nD)=1.636 (alpha). And sometimes also for beta and ...

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 ...
