Question

The angle of incidence for a ray of light at a refracting surface of a prism is 45° . The angle of prism is 60°. If the ray suffers minimum deviation through the prism, the angle of minimum deviation and refractive index of the material of the prism respectively, are:(a) 45°, 1/√2(b) 30°, √2(c) 45°, √2(d) 30°, 1/√2
