The Electromagnetic Spectrum
All about colour...

White light is made up of all the colours of the rainbow. When white light hits a more optically dense material, it bends or refracts and the speed of the light changes. Each colour refracts a slightly different amount and as a result, we are able to see all the seven colours of visible light. This is called "dispersion".
