OP2.1 Brewster's Law

Here the vu graph is used as the source of light which is unpolarized. Using a piece of glass to reflect the light before it hits the mirror in the vu graph, any transmitted light will be polarized slightly. The angle A at which this is greatest obeys Brewster's law: tan A = n'/n, where n' is the refractive index of the second medium and n is that of the first medium, in this case air.
