Chapter 3, Problem 3.5.43(choose chapter or problem)
Let be the velocity of light in air and the velocity of light in water. According to Fermats Principle, a ray of light will travel from a point in the air to a point in the water by a path that minimizes the time taken. Show that where (the angle of incidence) and (the angle of refraction) are as shown. This equation is known as Snells Law.
