A sphere of refractive index 2 is kept in a space whose centre is O A ray is incident at point A of the sphere and after refraction at A it is internally reflected at point B then refracted at C and finally comes out from the sphere It is given that in then find the total deviation produced in the incident ray is minimum if the angle of incidence is given by i sin 1 the value of 1 B
