Thank you for understanding what I meant and answering with a good explanation...

Please tell me if I am right... First there are alternations of E in every direction...When it goes through Calcite the calcite polarizes it... We take two planes perpendicular to each other(principal plane and the other perpendicular to it) and find out the vertical and horizontal component... And as calcite not isotropic regarding the structure of molecules thus the refractive index is not same in the 2 planes... Thus the ray splits into two rays having different velocity and goes different direction...

btw: Why don't we talk about magnetic field alternation when talking about polarization and regarding phenomena?
