State Brewster's law.
The value of Brewster angle for a transparent medium is different for light of different colours. Give reason.

Text Solution

Verified by Experts

For Brewster.s law it is clear that value of polarising angle depends on the refractive index of the medium. As refractive index of a medium is different for light of different colours, hence it is obvious that value of polarising angle is different for light of different colours.
