Chapter 25, Problem 27PE
A light ray entering an optical fiber surrounded by air is first refracted and then reflected as shown in Figure 25.55. Show than if the fiber is made from crown glass, any incident ray will be totally internally reflected.
Figure 25.55 A light ray enters the end of a fiber, the−surface of which is perpendicular to its sides. Examine the conditions under which it may be totally internally reflected.
