The Science and Beauty of Rainbows
TLDR Rainbows are created when white sunlight hits a prism or raindrop, slowing down, bending, and spreading out into its component wavelengths. They can have different numbers of colors and can even form a full circle depending on perspective and location.

Double rainbows occur when the second refraction of light is reversed, with the red on the bottom, and triple and quad rainbows are rare but can be seen if the primary rainbow is sharp and the raindrops reinforce each other.

A real rainbow can be a full circle depending on your perspective and location, and pilots can often see full circle rainbows from above.
