3. In Fig. 2, if we increase the index n, but keepn, <n,, should the value of increase or decrease? Give your reasoning. Total Internal Reflection When light passes from a medium of large refractive index into one of small refractive index --- for example, from water to air --- the refracted ray bends away from the surface normal, as shown in Fig. 2. As the angle of incidence increases, the angle of refraction also increases. When the angle of...
