The electromagnetic spectrum contains many types of waves, one of which is infrared waves. Other electromagnetic waves include gamma rays, x-rays, ultraviolet, visible light, microwaves, and radio. Infrared waves are electromagnetic radiation of a particular wavelength or color that we have named 'infrared.' They are between 700 nm (nanometers) and 1 mm. Note that 1 mm is equal to 1,000,000 nanometers. They are just beyond what our eyes can detect on the red side of the rainbow.
Abbr. IR. 1. Of or relating to electromagnetic radiation between microwaves and red visible light in the electromagnetic spectrum, having frequencies between 300 gigahertz and 400 terahertz and wavelengths between 1 millimeter and 750 nanometers.2.nfrared. n. 1. (General Physics) the part of the electromagnetic spectrum with a longer wavelength than light but a shorter wavelength than radio waves; radiation with wavelength between 0.8 micrometres and 1 millimetre. adj.
