Where do rainbows come from?

Light bends as it travels from one location to another, due to the different speeds at which it travels through different mediums. This process of natural bending is referred to as refraction. When light passes through a prism, the different colors of the light refract out at different angles, dispersing and becoming individually visible to the human eye. The same principle applies when light passes through a droplet of water in the air. If enough light passes through enough droplets in a confined area, the refracted pattern of light is visible to humans as a bent stripe of multiple colors, known everywhere as a rainbow.
A prism separates white light into its component colors. For simplicity's sake, this diagram shows only red and violet, which are on opposite ends of the spectrum.
