Let vi be the velocity of light in air and vz the velocity of light in water. According to Fermať'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 ACI that minimizes the time taken. Show that sin 61 sin 02 V2 where 0, (the angle of incidence) and 02 (the angle of refraction) are as shown. This equation is known as Snell's Law.
