1. π 2. π, reflects in the fast axis 3. π/2, linear to cicular and vice versa 4. If their fast axes are aligned, would produce total phase difference 3π/2

I've now edited the original problem so it is complete - that all the information given though! For part (a) I get an elliptical shape with maximum (1,1) and minimum (-1,-1), and anticlockwise in direction. Part (b) is asking to convert this to horizontal polarisation using 1/2 and 1/4 wave...

(a) The polarisation pattern is elliptical with maximum (1,1) and minimum (-1,-1), and anticlockwise in direction. (b) I know the solution is a quarter-wave plate oriented π/4, and half-wave plate at π/16, but don't understand how to reach there. I've obtained the polarisation vector (cos π/8...
