Degree of linearly polarized light for both reflected and refracted light as a function of incident angle. In this example, air (n1 = 1) and glass (n2 = 1:5) are the two indices of refraction. The maximum degree of linear polarization occurs at the Brewster angle, information that can be used to identify the index of refraction of a material.
