Question

26. What is polarisation of light? Under what condition does a beam of light reflected by a transparent
medium become plane polarised? Use this condition to establish a relation between the angle of
incidence and the refractive index of the transparent medium.

Answer 1

Explanation:

Polarization : A light wave that is vibrating in more than one plane is referred to as unpolarized light.

Polarized light waves are light waves in which the vibrations occur in a single plane.

The process of tiantforming unpolarized light into polarized light is known as polarization.

It state that the tangent of the polarization angle of incidence of a transparent medium is equal to the refractive index of the medium.
