An equilateral triangular prism is made of glass `(mu = 1.5)`. A ray of light is incident normally on one of the faces. The angle between the incident and emergent ray is

Calculate the refracting angle of a prism (mu = sqrt2) if a ray of light incident normally on one of the face emerges from the other face just grazing it.

The refracting angle of a glass prism is 30^@. A ray is incident onto one of the faces perpendicular to it. Find the angle delta between the incident ray and the ray that leaves the prism. The refractive index of glass is mu=1.5.
