Monochromatic light impinges on a micaplate, perpendicularly to its opticalaxis. If the thickness of the plate is adequate (l/4 plate), a phase shift of 90° occurs between the ordinary and the extraordinary beam when the latter leaves the crystal. The polarisation of exiting light is examined for different angles between the optical axis of the l/4 plate and the direction of polarisation of incident light. Measurement of the intensity of linearly polarised light as a function of the analyser's position (Malus' law). Measurement of the light intensity behind the analyser as a function of the angle between the optical axis of the l/4 plate and the analyser. Carrying out experiment (2) with two successive l/4 plates.
