purplebat60Lv1in Mathematics·25 May 2020Let be the velocity of light in air and 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 thatwhere (the angle of incidence) and (the angle of refraction) are as shown. This equation is known as Snell’s Law.
