A, B and C are the parallel sided transparent media of refractive index n1, n2 and n3 respectively. They are arranged as shown in the figure. A ray is incident at an angle q on the surface of separation of A and B which is as shown in the figure. After the refraction into the medium B, the ray grazes the surface of separation of the media B and C. Then, Sin q = ______.parallel sided transparent media(A)(B)(C)(D)
