At a wavelength of 400nm, the semiconductor ZnSe has a complex refractive index n= 3.0+0.32i
A) If 400nm is incidient from air onto ZnSe with θ=tan-1(NR) = 71.6°,
What is the refraction angle of the transmitted wave?
B) Calculate the magnitude R and phase shift ψ associated with the amplitude reflection coefficient r for p-polarized 400nm radiation incident at 71.6°
C) If 400nm radiation with a unit polarization vector 1/√2[1 0] is incident at 71.6 on the air-ZnSe interface, find the unit polarization vector that describes the reflected radiation.

The Attempt at a Solution
For part a, i tried using snell's law and just omitted the imaginary part, I'm not sure if it's the right answer because of that though. For the others, I have no idea where to start.
