Problem
Unpolarised light of irradiance I0 passes through the following train, in order: (a) an ideal linear polariser with its transmission axis along x (0 degrees); (b) an ideal retarder of retardance Γ=π/2 with its fast axis at 30 degrees to x; (c) an ideal linear polariser with its transmission axis at 90 degrees to x. Find the irradiance transmitted by the whole train, as a fraction of I0.
