Document Title: Double rainbow (DI01454) Photo by Carlye Calvin
Description: When direct sunlight strikes falling rain, a rainbow is seen at a point directly opposite the sun. Some of the light entering the raindrop is refracted into its component colors, reflected off the back interior wall of the drop, and refracted again as it exits the drop.
