A paralIel beam of unpolarized light is incident on a plane glass of refractive index 1.60 at an angle to the normal. If the reflected beam is completely polarized, calculate the angle of incidence of the beam.
tan\(\theta = \mu \text{(Brewsters law)}\)
\(\theta tan^{-1} = \mu = tan{-1} 1.60 = 58^o\)
