Question

Rainbows are formed when sunlight is refracted, or bent, and then reflected inside raindrops. This refraction and reflection cause the light to separate into its different colors, creating the spectrum of colors we see in a rainbow.

Rainbows are formed when sunlight is refracted, or bent, as it passes through raindrops in the air. This refraction causes the sunlight to separate into its different colors, creating the visible spectrum of colors that we see in a rainbow.
