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.
