Question

Calculate the angle of refraction of wood for a ray of light of wavelength 589.3 nm which is incident at polarizing angle. Find out the Brewster’s angle of light which travels from vacuum to glycerine.

Answer 1

Explanation:

Brewster's angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.

The Brewster's angle is given as
