Rainbows form after storms when sunlight shines through raindrops in the atmosphere. The raindrops act as prisms, refracting and reflecting the light, which separates it into its constituent colors. For a rainbow to be visible, the sun must be behind the observer, and the rain must be in front, allowing the light to create the circular arc of colors. Thus, the combination of sunlight and moisture creates the beautiful phenomenon of a rainbow.
