Malus' law

Article no. P2250401 | Type: Experiments

University

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

  1. The plane of polarisation of a linear polarised laser beam is to be determined.
  2. The intensity of the light transmitted by the polarisation filter is to be determined as a function of the angular position of the filter.
  3. Malus' law must be verified.

Learning objectives

  • Electric theory of light
  • Polarisation
  • Polariser
  • Analyser
  • Brewster's law
  • Malus' law
