A glass prism has a refractive angle of `90^(@)` and a refractive index of 1.5. A ray is incident at an angle of `30^(@)`. The ray emerges from an adjacent face at an angle of

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.

The face AC of a prism ABC of refracting angle 30^@ is silvered . A ray is incident on face AB at an angle of 45^@ as shown in figure . The refracted ray undergoes reflection at face AC and retraces its path . The refractive index of the prism is
