A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. By rotating the prism,the angle of minimum deviation is measured to be 40^(@) . What is the refractive index of the material of the prism? If the prism is placed in water (refractive index 1.33), predict the new angle of minimum deviation of a parallel beam of light. Refracting angle of the prism is 60^(@) .
