Ask Storm Team 11: How do Rainbows Form



Today’s question comes from Christian Walton:  How do rainbows form?

Rainbows are more prominent during the spring and summer months with longer days and a weather set-up where scattered showers and storms are more common. Rainbows develop when sunlight hits raindrops falling through the sky. Sunrise and sunset are times when the refraction process is maximized. Light enters the rain droplet creating a bending of the light called refraction, then the ray of light reflects within the droplet, followed by a refraction process as light emits from the rain droplet. This process produces a beautiful array of color. To ask Storm Team 11, click here to submit your question
