When white light passes through a prism, it refracts and separates into the visible color spectrum of red, orange, yellow, green, blue, indigo, and violet. This document discusses the refraction of light through prisms and how rainbows are formed by the reflection and refraction of sunlight within water droplets in the sky. It aims to correct the misconception that rainbows are produced by only one droplet and provides links to videos explaining how to make rainbows and why the man stands with his back to the sun to see one.
