A and B are two parallel sided transparent slabs of refractive indices n_1 and n_2 respectively. A ray is incident at an angle theta on the surface of separation of A and B and after refraction from B into air grazes the surface of B. Then sin theta =1/(n_2) sin theta=1/n_1 sin theta =n_2/n_1 sin theta =n_1/n_2
