After a rain shower you can usually see a rainbow in the sky. If you shine light through a prism you see a rainbow or more correctly the colour spectrum
red light is monochromatic light and if it shines on a prism its still red light pass through the prism, not 'rainbow' color.
White light separates into seven colours
They separate light into the light spectrum. If a beam of light shines through a prism, a rainbow of color will show out through the opposite side.

Wow that prism sure makes some pretty colors when light shines through it!
The water acts like a prism and white light shines through it, it makes a rainbow.

The diamond acts as a prism breaking the light into different wavelengths.
They both involve a spectrum. If you shine light through a prism, it splits it up into the 7 colours of the rainbow. Rainbow is created when light shines through water, so rainbow is just another word for a spectrum. See? GCSE Physics pays off! =)
