Re: Please. There are not two Suns. What you see is Birefringence
Tell me if I am right.
When we say Birefringence we mean double refraction. The light enters the glass and depending on the angle that light will hit the glass, the ray is splitted to two separate light rays. In wikipedia, says that the refractive index of the birefringent material depends on the polarisation and propagation of light.
Does polarisation has anything to do with birefringence? Light that comes from the sun and hits the glass layer is unpolarised right? After double refraction occurs, the splitted rays become polarised.
I also read that ice has also birefringence properties and we know that there is ice attached to the glass.
So if I am thinking this right. If light hits the glass layer and becomes polarised and then the polarised light hit the ice layer whose refractive index depends both on polarisation and incoming angle, then what will be the result? For example, we will see the refracted rays (sun) further apart?
Yes indeed, i mention the polarization of light in the videos on birefrigence.
