A light ray is incident normally on one of the refracting faces of a prism and just emerges out grazing the second surface. Then, the relation between angle of the prism and its critical angle is

A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?

A monochromatic ray of light is incident normally on one of the refracting surfaces of a prism . The emergent ray grazes the second refracting surface . What is the angle of the prism if the refractive index of the material of the prism is 1.6 ?

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—

A ray of light is incident normally on one of the refracting surfaces of a prism of refracting angle A,. The emergent ray grazes the other refracting surface. Find the refractive index of the material ofprism.

If a light ray incidents normally on one of the faces of the prism of refractive index 2 and the emergent ray just grazes the second face of the prism, then the angle of deviation is

If a light ray incidents normally on one of the faces of the prism of refractive index 2 and the emergent ray just grazes the second face of the prism, then the angle of deviation is
