Rainbow Optics

Abstract

The fundamental and well known characteristics of rainbows are explained using Snell’s law of refraction and simple geometric considerations involving interaction between white light in the form of rays and a raindrop of water. The sequence of colors and the form of the arc were derived. Also, considerations are presented about the size of the arc and the formation of the secondary arc.
