Question

Quizplus · Accepted Answer

The primary rainbow is produced by the reflection, refraction, and dispersion of light as it enters a raindrop and then exits back out. The secondary rainbow is produced by a double reflection of light inside a raindrop, creating a second, dimmer bow. The type of precipitation (rain or frozen) does not affect the creation of the rainbows.
