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 Deter mine the refractive index of the material of the prism
