Question

What causes the formation of rainbows?

Answer 1

Rainbows are formed when sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere. The sunlight breaks into its component colors due to the dispersion effect, creating the colorful arc in the sky that we see as a rainbow.

Answer 2

Rainbows are formed when sunlight is refracted, or bent, in millions of raindrops in the sky. This refraction separates white sunlight into its different colors, creating the beautiful spectrum of colors that we see in a rainbow.
