Fresnel's Rhomb and polarization

[tuomas22]

Homework Statement

alpha = 54.6 degrees

I need to calculate phase difference between E(perpendicular) and E(parallel) polarization components.

Homework Equations

The Attempt at a Solution

Problem is I don't know any relevant equations!
Can I get the phase difference from Fresnel coefficients somehow??
Or actually I don't know even how to get the polarization components calculated.

So if someone could point me to right direction it would be much appreciated!
