How they form

Rainbows form when light enters a raindrop and slows down in a process called refraction. It then hits the back of the rain drop and is reflected then exits the rain drop from a different angle through refraction again.

This process causes sunlight to separate into different colors of the visible light spectrum.

How do double rainbows form?

Double rainbows can form when the light is reflected twice in the raindrop. The primary rainbow is a result of the light bring reflected at a lower angle. The secondary rainbow is a result of light reflected at a higher angle.

Why are they in an arc?

Since raindrops are circular, they reflect light in a circular pattern. We only see half of the circle because the other half is blocked by the earth.
