Visible Light! Any electromagnetic wave that the human eye can detect. Called the Visible Spectrum.
- white light breaks into the colours of a rainbow when it passes through a prism. - white light is made of all the colours of the visible spectrum

The Visible Light Spectrum is a very small part of a much larger spectrum called the Electromagnetic Spectrum
