Define the angle of incidence and angle of reflection.

What is the relation between the angle of incidence and the angle of reflection?

What is the angle of incidence and angle of reflection when a ray of light is incident normally on a mirror?

Draw 180^@ and 90^@ deviation in a prism.

Find the angle of incidence of a ray of light on one face of a 60°.prism, if the ray is just totally reflected on meeting the opposite face (refractive index of glass = 1.5).

A beam of unpolarised light is incident on a transparent mediuam .What should be the angle of incidence , so that partially reflected ray is completey polarised ?

The angle of minimum deviation produced by a 60 o prism is 40 o . Calculate the refractive index of the material of the prism.

Unpolarised light is incident on a plane glass . What should be the angle of incidence , so that the reflected light is perfectly polarided ? [mu=(3)/(2)]

Plot the graph of a angle of deviation (delta) versus angle of incidence (i) for a triangular prism.

A ray of light passes through an equilateral prism such that the angle of incidence is equal to the angle of emergence and the latter is 3/4 th of the angle of prism. Calculate the angle of minimum deviation and refractive index.
