Derive an expression for the anle of deviation of a small prism in terms of the refractive index and the angle of the prism.

Draw a ray diagram to show the refraction of light through a glass prism. Hence obtain the relation for the angle of deviation in terms of the angle of incidence, angle of emergence and the angle of the prism.

Write expression for the angular dispersion produced by a prism.

A thin prism of 2^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 20^@ angle gives a deviation of 1^@ . What is the value of refractive index of the material of the prism?

A thin prism of 5^@ angle gives a deviation of 3.2^@ .What is the value of refractive index of teh material of the prism?

Derive a relation between refractive index and critical angle.

What is a prism, refracting faces and angle of prism?

For a glass prism (mu=sqrt 3) the anlge of minimum deviation is equal to the angle of the prism. Find the angle of the prism.

Write deviation formula for prism.
