Show how light reflected from a transparent medium gets polarised. Hence deduce Brewster's law.

Critical angle between a given transparent medium and air is theta_( c) . A ray of ligth in air enters the transparent medium at an angle of incidence equal to the polarising angle. Deduce a relation between angle of refraction r and critical angle theta_(c ) .

A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence of 45^(@) . The ray undergoes total internal reflection. If mu is the refractive index of the medium with respect to air, select the possible values (s) of mu from the following

A monochromatic ray of light is refracted from vacuum to a medium of refractive index mu . Determine the relation of the wavelengths of light in vacuum and in medium.

When light enters a denser medium from a rarer medium how it changes its direction?

When light travels from a rarer medium to a prism which is a denser medium, light ray bends towards the base of the prism. Is the statement true of false?

When light enters a rarer medium from a denser medium how it changes it direction?

A ray of light is incident on a glass. The reflected ray gets totally polarised. The magnitude of incidence angle is (refractive index of glass = mu )

If a ray of light is incident on a reflecting medium at the polarising angle, prove that the reflected and the refracted rays are at 90^(@) to each other.
