- A fish is 3.25 m below the surface of still water (Fig. P38.16). You do not want the fish to see your fishing boat. Is it possible to place your boat so that total internal reflection keeps it hidden from the fish? If so, explain how this is done. If not, explain why not. FIGURE P38.16 Problems 16 and 17.arrow_forwardConsider sunlight entering the Earth's atmosphere at sunrise and sunset-that is, at a 90° incident angle. Taking the boundary between nearly emptyspace and the atmosphere to be sudden, calculate the angle of refractionfor sunlight. This lengthens the time the Sun appears to be above thehorizon, both at sunrise and sunset. Now construct a problem in which youdetermine the angle of refraction for different models of the atmosphere,such as various layers of varying density.
