The rainbow is one of the more spectacular light shows observed on earth. The traditional rainbow is sunlight spread out into its spectrum of colors and diverted to the eye of the observer by water droplets. The "bow" part of the word refers to the fact that the rainbow is a group of nearly circular arcs of color all having a common center. Typically, we only see a portion of the entire circle, leading to the bow shape.
