Malus’ law
Linear polarised light passes through a polarisation filter. Transmitted light intensity is determined as a function of the angular position of the polarisation filter.
- the principle that Polaroid glasses work on

- 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.
