A cubic block of glass of refractive index n = 1.5 has its upper face covered with liquid of unknown refractive index. It is observed that when the upper face is illuminated by a diffuse source, i.e., a source providing rays traveling in all directions, rays of light emerge through the side face only at angles 6 greater than 45°. What is the refractive index of the liquid?
