One of the most well-known physical laws related to polarization is Malus’s Law. This law states that the intensity of plane-polarized light passing through a rotatable polarizer analyzer varies as the square of the cosine of the angle through which the analyzer is rotated from the position giving maximum intensity. The lesson described here allows you to verify Malus’s Law using PocketLab Voyager and one of the light polarizers contained in the PocketLab Scientist Kit.
