Exercise 5 (a.) For light travelling in a medium of refractive index n, and incident on the boundary with a medium of refractive index n2, explain what is meant by total internal reflection and state the circumstances in which it occurs. (b.) A cube of glass of refractive index 1.500 is placed on a horizontal surface separated from the lower face the cube by a film of liquid, as shown in the diagram. A ray of light from outside and in a vertical plane parall to one face of the cube strikes another vertical face of the cube at an angle of incidence of i = 48° 27' and. after refraction, is totally reflected at the critical angle at the glass-liquid interface. Calculate (i.) the critical angle at the glass-liquid interface and (ii.) the angle of emergence of the ray from the cube.
