It is true that visible spectrum of light that humans see is merely a narrow portion of the larger spectrum of electromagnetic radiation.

Visible radiation has wavelength between 380 to 740 nanometers.

the radiation which have wavelength below 380nm and above 10nm is known as ultravoilet radiation

the radiation which have wavelength between 740nm to 1mm is known as infrared radiation.
