What is the light that is not visible to the human eye?

Answer:
The human eye can only see light waves that have a wavelength between 400 and 750 nanometres approximately. Anything with a lower wavelength (Ultraviolets, X-rays, Gamma rays) or with a high wavelength (Infrareds, radio waves) cannot be spotted by the human eye.
