Answer 2

Rainbows form when sunlight is refracted, or bent, by raindrops in the atmosphere. The sunlight is dispersed into its spectrum of colors as it enters the raindrop and reflects off its inner surface, creating the vibrant colors of a rainbow. The light then exits the raindrop and is refracted again, producing the arc shape of the rainbow that we see.
