STATEMENT - 1 : The while light incident on a prism, after emerging from the prism will form a spectrum of rays.
and
STATEMENT - 2 : For different colours, a prism has different refractive indices.

Statement-1 : When a white light passes through a prism it forms a spectrum of seven colours. Statement-2 : The refractive index for different colour of light is different for the material of prism.

The Splitting of different colours of light in a prism is:

STATEMENT - 1: A light ray passing though a prism it suffers minimum deviation, if after refraction the refracted ray becomes parallel to the base of the prism. and STATEMENT - 2 : In the case of minimum deviation angle of incidence is equal to angle of emergence.

A ray of light incident at an angle theta on a refracting face of a prism emerges from the other face normally. If the angle of the prism is 5^@ and the prism is made of a material of refractive index 1.5 , the angle of incidence is.

Assertion : A priam is the source of colours of light. Reason : A prism has same refractive index for different colours of light.

A ray of light is incident at an angle of 60^(@) on one face of a 30^(@) prism . The emergent ray from the prism makes an angle of 30^(@) with the incident ray. The angle of emergence and refractive index of the material of the prism are-

A ray of monochromatic light is incident on the refracting face of a prism (angle 75^(@)0 . It passes through the prism and is incident on the other face at the critical angle. If the refractive index of the prism is sqrt(2) , then the angle of incidence on the first of the prism is
