प्रश्न
State Brewster’s law of polarization of light.
उत्तर
Brewster’s law states that the tangent of the angle of polarization is equal to the refractive index of the medium.
i.e., μ = tan lp, where p is the refractive index and lp the polarizing angle.

Derive the expression of Brewster's law when unpolarised light passing from a rarer to a denser medium gets polarised on reflection at the inteface.
The value of Brewster's angle for a transparent medium is different for light of different colours. Give reason.
Ordinary (i.e. unpolarized) light is incident on the surface of a transparent material at the polarising angle. If it is partly reflected and partly refracted, what is the angle between the reflected and the refracted rays?
State Brewster’s law and show that when light is incident at polarizing angle the reflected and refracted rays are mutually perpendicular to each other.
