82 - The Law of Malus
In this lab assignment, you will investigate the law of Malus which states the following: For a polarized light beam, which passes through a polarizer, the intensity after the polarizer depends quadratically on the cosine of the angle between the light's initial polarization direction and the axis of the polarizer.
