Principle

Linear polarised light passes through a polarisation filter. Transmitted light intensity is determined as a function of the angular position of the polarisation filter.

Benefits


the principle that Polaroid glasses work on

introductory yet quantitative experiment to polarization

straightforward simple setup



Tasks


The plane of polarisation of a linear polarised laser beam is to be determined.

The intensity of the light transmitted by the polarisation filter is to be determined as a function of the angular position of the filter.

Malus’ law must be verified.
