A rainbow is formed when white light (such as sunlight) passes through water droplets, ice crystals, or glass. The light rays are refracted, or bent, by different amounts depending upon their wavelength. This has the effect of spreading the white light out into a broad band of the colors making up the white light.
In February 2009 the Explorers spent a session investigating the nature of light. They learned that white light is actually anything but white, and that nearly every beam of light has a secret rainbow hiding inside it.
