Rainbows are formed when rain drops refract or bend sunlight and reflect the colours back to you.
Sunlight is made up of rays of light that are different colours; red, orange, yellow, green, blue, indigo and violet.
Each of the 7 colours that make up white light is bent at a different angle when the light hits a drop of water, so the 7 colours show up separately.
A prism works like a raindrop to bend light so you can see the colours of a rainbow.

A rainbow is an optyical illusion and does not actually exist in the sky. The angle and position of it in the sky depends on the location and position of the person looking at it.
