Facts about rainbows

Rainbows are simply beautiful multicoloured arcs of light in the sky. Rainbows occur when it's both raining and the sun is shining simultaneously. To see a rainbow, you must stand with your back to the sun, otherwise it will not be visible.
Our sun gives off light, which we see as 'white light'. But in fact, it isn't actually white at all, it is actually numerous different colour wavelengths. The main colours it gives off are red, orange, yellow, green, blue, indigo and violet. These colours are called the colours of the spectrum. This is often remembered by the mnemonic 'Richard Of York Gave Battle In Vain'.
As an experiment, you can use a prism to separate these seven colours of the spectrum from the white light we see.
