Let v1 be the velocity of light in air and v2 the velocity of light in water. According to Fermat’s Principle, a ray of light will travel from a point A in the air to a point B in the water by a path ACB that minimizes the time taken. Show that
where θ1 (the angle of incidence) and θ2 (the angle of refraction) are as shown. This equation is known as Snell’s Law.
