Definition

Thermal radiation, transmitted as electromagnetic wave energy, is a form of heat transfer generated by any matter having a temperature higher than absolute zero.

Basic Concepts and Properties of Thermal Radiation

Thermal radiation is one of the three basic forms of heat transfer (conduction, convection, and radiation), being a basic property of matter depending on its temperature. In microcosmic point of view, thermal radiation is the result of random particle motion (due to the material temperature) resulting in charge acceleration or dipole oscillation of the electrons and protons.

In contrast to conduction and convection, thermal radiation has two unique properties: (1) it does not require a medium to be transferred but being electromagnetic energy can interact with intervening materials; and (2) during the emission/absorption of radiation, there is transfer between electromagnetic energy and kinetic energy of atoms, namely, thermal energy. These two properties result...
