Rainbow


The most charming example of chromatic dispersion is a rainbow. When white sunlight is intercepted by a drop of water in the atmosphere. Some of the light refracts into the drop, reflects from the drop's inner surface, and then refracts out of the drop. As with the prism, the first refraction separates the sunlight into its component colors, and the second refraction increases the separation. And the rainbow is there in the sky. This applet shows the physics of rainbow.
