On the other hand, the infrared lights are the radiations that are comprised of wavelength ranging from about 700 nm to 1 mm (millimeter). These infrared lights have a higher wavelength in comparison to the visible light.
Those lights that are comprised of wavelength higher and shorter than the visible light wavelength are not visible to the naked eye. Human eyes respond to the light only between red and violet light of the electromagnetic spectrum.
