Web26 mei 2016 · Download chapter PDF. Heat transfer by thermal radiation is transfer of heat by electromagnetic waves. It is different from conduction and convection as it requires no matter or medium to be present. The radiative energy will pass perfectly through vacuum as well as clear air. While the conduction and convection depend on temperature ... WebHeat is transferred by radiationwhen surfaces exchange electromagnetic waves, such as light, infrared radiation, UV radiation or microwaves. Radiation does not require any fluid medium or contact, but does require an air gap or other transparent medium between the surfaces ex- changing radiation.
