The maximum energy in the thermal radiation from a hot source

SpletUnder normal circumstances, a theory known as the blackbody limit governs the maximum amount of energy that can be transferred by thermal radiation. But at the nanoscale, those limits break down: When nanosized components are very close to one another, thermal transfer between them expands dramatically. SpletRadiation is the transfer of heat energy from a region of high temperature to a region of low temperature by infrared radiation. Unlike conduction and convection, radiation takes place without the ... SpletThe maximum energy in the thermal radiation from a hot source occurs at a wavelength of 1 1 × 1 0 − 5 cm.
