A, B and C are the parallel sided transparent media of refractive indices n1, n2 and n3, respectively. They are arranged as shown in the figure. A ray is incident at an angle i on the surface of separation of A and B as shown in the figure. After refraction in the medium B, the ray grazes the surface of separation of the media B and C. Then, sini is equal to,
