Question

State brewster's law the value of brewster angle for a transparent medium is different for light of different colours give reason

Answer 1

Explanation:

Brewsters Law

As the Brewster's Law states that we can achieve the maximum polarization of light by allowing the ray to fall on a transparent medium's surface so that the refracted ray becomes perpendicular to the reflected ray. It develops a relationship between the polarizing angle ip and the refractive index.

As lights of different color ss have different wavelength , hence have different values of refractive index of medium. that is why.
