Question

The ratio of reflected intensity to the incident intensity at normal incidence from
medium having refractive index n1 to n2 is​

Answer 1

Answer:

at a dielectric interface from n1 to n2, there is a particular angle of incidence at which Rp goes to zero and a p-polarised incident wave is purely refracted. This angle is known as Brewster's angle, and is around 56° for n1 = 1 and n2 = 1.5 (typical glass).
