| Colour is a natural phenomenon that is present in visible light on the electromagnetic spectrum. Visible or white light surrounds us all the time, but when light is broken (e.g. by a prism), shorter wavelengths have a greater angle of refraction and we are able to see the colours that make up white light. Raindrops act as a prism and therefore the well known effect of the rainbow. |

Light is part of the electromagnetic spectrum. Visible light is made up of the wavelengths between 400 and 700 nm. An object reflecting the shorter wavelengths appears blue, whereas one reflecting the longer wavelengths appears red. We use these descriptors to describe the wavelengths of light. |
