A ray of light travelling in glass 3 2 is incident on a horizontal glass air surface at the critical angle 8c If a thin layer of water 4 3 is now poured on the glass air surface the ray of light emerge into air at the water air surface at an angle of k radians from the normal at that point find the value of k C A Water O R 0c R u 3 2 D B
