Minimum Time When light waves, traveling in a transparent
Chapter 3, Problem 52(choose chapter or problem)
Minimum Time When light waves, traveling in a transparent medium, strike the surface of a second transparent medium, they change direction. This change of direction is called refraction and is defined by Snells Law of Refraction, where and are the magnitudes of the angles shown in the figure and and are the velocities of light in the two media. Show that this problem is equivalent to that of Exercise 51, and that light waves traveling from to follow the path of minimum time. x34x
