Obtain a relation between a critical angle and refractive index of medium.

State Brewster's law. Obtain the relation between the Brewster angle and refractive index for medium which produces Plane Polarized light.

What is the relation between critical angle and refractive index? What is critical angle for diamond?

State Brewster.s law. Obtain the relation between the polarising angle and refractive index for the given pair of media.

Define refractive index?

A ray of light incident on the horizontal surface of a glass slab t 70^@ just grazes the adjacent vertical surface after refraction. Compute the critical angle and refractive index of the glass.

The refractive index of diamond is:

Define absolute refractive index.
