Today’s Topics. Huygens’ principle and refraction. Snell’s law and applications. Dispersion. Total internal reflection. Huygens’ Principle. Newton’s contemporary Christian Huygens believed light to be a wave, and pictured its propagation as follows: at any instant, the wave front has reached a certain line or curve. From every point on this wave front, a . Lecture 1. Michael Fowler. Basic Outline. The course has three main parts, each about a month: . Electrostatics.. Magnetism and Magnetic Induction..
