    Brewster’s law:- Brewster’s law states that at any particular angle of incidence, reflected ray is completely polarized; and the angle between reflected and refracted ray is 900.

    • At i = iB; where iB = Brewster’s angle of incidence.
    • From Snell’s law :- (sin i/sin r)= μ
    • => sin iB /(sin (π/2 -iB))
    • =>(sin iB /cos iB)=μ
    • tan iB = μ
