How can we separate these colours? Such an instrument that does so is called a "Spectroscope", which uses a phenomenon called "diffraction", to split light into its constituent colours.

The CD by itself is an excellent spectroscope, as the closely placed optical lines act as a perfect diffraction grating. Here, we create a cardboard encasing for the CD and point it towards any light source to then see emission spectral lines, i.e. the light split into its constituent colours.
