Infrared radiation is commonly referred to as what?

Infrared radiation is commonly referred to as thermal or heat radiation because it is a type of electromagnetic radiation whose wavelengths are longer than those of visible light but shorter than those of microwaves. The range of infrared radiation is associated with the thermal properties of objects, where it is emitted as heat. When objects absorb heat, they increase in temperature and emit infrared radiation, which is characterized by longer wavelengths that fall within the infrared spectrum.

This association with heat is practical in various applications, such as thermal imaging and heating technology, where detecting or utilizing infrared radiation allows for the measurement of temperature or the transfer of heat. Understanding this concept is crucial in fields ranging from meteorology to engineering, emphasizing the importance and utility of infrared radiation in practical situations.
