A ray of light goes from point A in a medium in which the speed of light is v 1 to point V in a medium in which the speed of light is v 2 . 1. What is the time required to go from A to B ? 2. Show that the time reaches its minimum when n 1 sin T 1 =n 2 sin T 2 (so that the actual path the light takes minimizes traveling time!) Solution A. The time requires is given by the distances divided by corresponding velocities 2 2 2 2 1 2 1 2 x h l h t v v ± ± ± B. Consider arbitrary path. Then the time needed is given by 2 2 2 2 1 2 1 2 ( ) ( ) ( ) x z h l z h t z v v ± ± ² ± ± Let us consider this as a function of deviation z and require to find such
