Light ray is incident on a prism of angle A=60^(@) and refractive index mu=sqrt(2) .the angle of incidence at which the emergent ray grazes the surface is given by

Calculate the angle of incidence on the face of a prism of refracting angle 60^(@) and of refractive index 1.5, for which the emergent ray just grazes the other face.

Calculate the angle of incidence on the face of a prism of refracting angle 60^(@) and of refractive index 1.5, for which the emergent ray just grazes the other face.

A ray of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt 2 . The angle of deviation of the ray is

A ray of light is incident normally on one of the faces of a prism of angle 30^@ and refractive index sqrt2 . The angle of deviation of the ray is

A ray of light is incident on a prism of refractive index mu and angle A at the angle of incidence i_(1) and emerges at the angle i_(2) . If the ray is incident on the prism at the angle i_(2) , calculate the deviation of the ray.

The angle of a prism is 60^(@) When light is incident at an angle of 60^(@) on the prism, the angle of emerge is 40^(@) . The angle of incidence i for which the light ray will deviate the least is such that
