The plane of polarisation of a plane polarized light rotates by 60°...
Degrees when it passes through a certain material. This phenomenon is called optical rotation or Faraday rotation. The amount of rotation depends on the properties of the material and the wavelength of the light. It is commonly used in polarimeters and other optical instruments to measure the concentration or purity of a substance. Some materials have a natural ability to rotate the plane of polarisation, while others can be induced to do so by applying a magnetic field.
