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.

Infrared (IR) light is the part of the EM spectrum that people encounter most in everyday life, although much of it goes unnoticed.It is invisible to human eyes, but people can feel it as heat.R radiation is one of the three ways heat is transferred from one place to another, the other two being convection and conduction. Everything with a temperature above about 5 degrees Kelvin (minus 450 degrees Fahrenheit or minus 268 degrees Celsius) emits IR radiation.
