Question

10.A ray of light incident at an angle of 60^° on one face of Prism whose angle of Prism is 30^° . The ray emerging out of the Prism makes an angle 30^° with incident Ray. Show that emergent ray is perpendicular to the face through which it emerges and calculate the refractive index of the material of Prism.
