the heat that we sense being radiated from a hot surface like a hot piece of metal
*[[Sunlight]] falling on the surface of a [[planet]] is primarily in the visible part of the [[spectrum]]. However, the [[reflection]] of [[light]] from the surface tends to produce light of longer [[wavelength]] called [[infrared]] (IR) radiation (also known as radiant heat; IR radiation is the [[heat]] that we sense being radiated from a hot surface like a hot piece of metal).
