The polarization of quarter-wave plate. 2.5.01-00

Get the concept of:
Quarter-wave plate, a light wave with circular and elliptical polarization, polarizer, analyzer, the plane of polarization, double refraction, the optical axis, the ordinary and extraordinary ray

Experiment:
Monochromatic light falls on the plate of mica perpendicular to the optical axis. At an appropriate thickness of the plate (λ / 4 or a quarter wavelength) observed phase shift value of 90 ° between the ordinary and extraordinary rays, when the light comes out of the crystal. Study polarization of light coming out at different angles between the optical axis of the plate and the polarization direction of incident light.
