Question

State and explain Brewster’s law. The refractive index of a medium is √3. Find the polarizing angle for a beam of unpolarized light incident on it from air.

Answer 1

Brewster's law states that relationship for light waves stating that the maximum polarization  of a ray of light may be achieved by letting the ray fall on a surface of a transparent medium in such a way that the refracted ray makes an angle of 90° with the reflected ray.

Angle will be tan⁻¹($\sqrt{3}$)=60° according to Brewster's law.
