Monochromatic light with circular polarization falls normally on a crystalline plate cut parallel to the optical axis. Behind the plate there is a Nicol prism whose principal direction forms an angle ф with the optical axis of the plate. Demonstrate that the intensity of light transmitted through that system is equal to where δ is the




phase difference between the ordinary and extraordinary rays which is introduced by the plate.
