WebRadiation heat transfer is the transfer of heat from one body to another body in the form of electromagnetic waves. Most of these radiations lie in the infrared region. Unlike Conduction and Convection, radiation heat does not require any medium. All objects above absolute zero temperature emit radiation energy. WebThermal Radiation is the transfer of heat by the means of the electromagnetic radiation generated by the thermal motion of particles in matter. For most bodies on Earth, this electromagnetic radiation lies in the invisible region of the spectrum known as the Infrared region.
