Write the formula for the refractive index of the prism.

Define the term dispersion by a prism and give the reason for its occurrence .Write the formula for refractive index of the material of a prism in terms of the anle ofminimum deviation.

The dimensional formula for refractive index is

The dimensional formula for refractive index is

If minimum deviation is delta_m , for prism then refractive index of material of prism is ......

The refractive angle of prism is A. A ray is incident normally on one of the refracting faces of a prism and emerges out. If D be the deviation of the ray then refractive index of the material of the prism is—

The refractive index of the material of a prism is sqrt(2) and the angle of minimum deviation is 30^(@) . Calculate the value of the refracting angle of the prism.

Write the material required in finding the refractive index of a prism.
