The energy radiated by solids, liquids, and gases as a result of their temperature. Radiation is one of the three basic methods of heat transfer, the other two methods being conduction and convection. Heat radiation is conveyed in the form of electromagnetic waves and covers the entire electromagnetic spectrum, extending from radio waves through infrared, visible, ultraviolet, x-rays, and gamma-rays. From most hot bodies on Earth, this radiant energy lies largely in the spectrum's infrared region (Fig. 1).
