Dispersion

Summary: White light is made up of seven different bands of light. Each one is a different colour. You can use a prism to split (divide) white light into a spectrum. This is called dispersion. The spectrum of white light is continuous. This means there are no gaps between the colours. Sir Isaac Newton first did the experiment you can see in.
