Rainbows are actually pretty fascinating. They show up due to the
reflection of sunlight on water droplets in the air. The light is
refracted and reflected (you can look those up for your physics class)
and separates the sunlight into its full complement of colors. Double
rainbows indicate that the light in the droplets is actually being
reflected twice.
That's my take on it, I might not be completely clear on all the
interactions taking place between the light and the droplets.
Thanks for the question!
