Web11 Apr 2024 · Most of the solar radiation is absorbed by the atmosphere, and much of what reaches the earth's surface is radiated back into the atmosphere to become heat energy. Dark colored objects, such as asphalt, absorb radiant energy faster than light colored objects. However, they also radiate their energy faster than lighter colored objects. Web10 Feb 2024 · Answer: Radiant heat, also known as thermal radiation, is the transfer of electromagnetic radiation which describes the heat exchange of energy by photons. ... Radiant heat is a mechanism for heat transfer which does not require a medium in which it propagates (unlike convection and conduction). Advertisement.
