A ray of light enters a spherical liquid drop refractive index 3 from air at an angle of incidence 0 0 it suffers two internal reflections not TIR inside the drop and finally comes out of the drop If 0 0 is such that the deviation of the ray with respect to its original direction is minimum find the value of 12 sin 0
