Infrared: (of electromagnetic radiation) having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves.Infrared radiation has a wavelength from about 800 nm to 1 mm, and is emitted particularly by heated objects.
Ultraviolet: (of electromagnetic radiation) having a wavelength shorter than that <span>of the violet end of the visible spectrum but longer than that of X-rays.</span>
