Light traveling in glass with the index of refraction n1 of 1.52, is incident on a material with an index of refraction n2 of 2.35. Calculate the Brewster’s angle.

Answer 1

According to Brewster's law

tanip = n

here ip = Angle of polarization

in this question n = 1n2 = Refractive index of 2 with respect to 1

1n2 = n2/n1= 2.35/1.52= 1.546

ip = arc tan 1.546 = 55.1 degree
