WebBrewster’s Law. Brewster’s law is a relation between refractive index of a given medium and polarizing angle for the medium. This law is used to produce polarized light by reflection. In 1808, Malus discovered that when ordinary light is reflected from a surface of a transparent medium like glass or water, it becomes partly polarized.
