A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40^(@) . What is the refractive index of the material of the prism? The refracting angle of the prism is 606^(@) . If the prism is placed in water (refractive idex 1.33), predict the new angle of minimum deviation of a parallel beam of light.

A light ray falls on one of the faces of prism at an angle 40^(@) so that it suffers angle of minimum derivation of 30^(@) . Find the angle of prism and angle of refraction at the given surface.
