A ray of light is incident at an angle of `60^@` on the face of a prism having refracting angle `30^@.` The ray emerging out of the prism makes an angle `30^@` with the incident ray. Show that the emergent ray is perpendicular to the face through which it emerges.

A ray of light is incident at an angle of 60^(@) on one face of a prism of angle 30^(@) . The ray emerging out of the prism makes an angle of 30^(@) with the incident ray. The emergent ray is

A ray of light is incident at an angle of 60^(@) on a face of a prism with refracting angle 30^(@) . If the ray emerges from the other face and makes an angle of 30^(@) with the incident ray then, show that the emergent ray passes perpendicularly through the refracting surface. Determine the refractive index of the material of the prism.
