### thermodynamics - How does Infrared Relate to heat

2019-3-24 · The easiest answer is that below 3,000 Kelvin in temperature, heat radiates EM (often referred to as light by physicists although it is all EM not just visible light) in the infrared. Because most heat generates light in the infrared, scientists often refer to infrared light as heat. This is a generalized term or a convention.
