Answer:
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. William Herschel first discovered them around 1800.
We are surrounded by infrared every moment of every day. Warm objects, such as the human body, produce large amounts of infrared, and heat-sensitive CCTV cameras work by detecting these infrared waves. Half of the energy produced by the sun is infrared, so we are being bombarded by it constantly.
