WebDec 11, 2011 · Radiation is the transfer of heat by electromagnetic waves through a gas or vacuum. Heat transfer by this mode therefore requires a line of sight connection between the surfaces involved. All objects above absolute zero radiate heat energy; it is the net radiative heat transfer that is the heat transfer of interest. WebThe Radiation Mechanism Page 1 The Radiation Mechanism An intuitive understanding of the origins of radiation can be gained by associating radiation with the acceleration of charge. In fact, this notion can be mathematically proven from Maxwell’s equations, but it is beyond the scope of what we wish to discuss here. Instead, if we accept that
