The Phenomena and Applications of Light Dispersion

摘要

The article formulates the essence of the light dispersion phenomena in the classical theory view, and discusses the theory and experiments of the method of minimum deviation angle to measure the prism glass refraction. A empirical formula of deviation angle and the angle of incidence has been presented, and the formula can be used to find the exit light quickly and the emitted law of the exit light. It has provided theoretic foundation to accurately determine the position of minimum deviation angle. At last the author introduces the dispersion of light in the practical application.
