A ray of light is incident at 60^(@) on one face of a prism of angle 30^(@) and the emergent ray makes 30^(@) with the incident ray.the refractive index of the prism is

A ray of light incident at an angle of incidence 'I' passes through an equilateral glass prism such that the refracted ray inside the prism is parallel to its base and emerges from the prism at an angle of emergence 'e'. How is the angle of emergence 'e' related to the angle of incidence 'i' ?

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—

In an isosceles prism of prism angle 45^(@) , it is found that when the angle of incidence is same as the prism angle, the emergent ray grazes the emergent surface. Find the refractive index of the material of the prism.For what angle of incidence the angle of deviation will be minimum ?
