Question

Quizplus · Accepted Answer

When sunlight enters a raindrop, it refracts, or bends, due to the change in speed from air to water. The light then reflects off the inside of the raindrop and refracts again as it exits the raindrop, producing the colors of the rainbow. Therefore, there are two refractive events for each raindrop.
