thermal radiation
Noun
Meaning
thermal radiation (uncountable)
(physics) The electromagnetic radiation emitted from a body as a consequence of its temperature; increasing the temperature of the body increases the amount of radiation produced, and shifts it to shorter wavelengths (higher frequencies) in a manner explained only by quantum mechanics.
Synonyms
Examples
A normal thermometer would be significantly below convert, because the energy lost by thermal radiation would exceed the energy acquired from the atmospheric gas by direct contact.
As noted above, even low-frequency thermal radiation may cause temperature-ionization whenever it deposits sufficient thermal energy to raises temperatures to a high enough level.
In addition to the absorption of solar and thermal radiation, the atmosphere further gains heat by sensible and latent heat fluxes from the surface.
As it relates to the likelihood of nuclear winter, the hazard from thermal radiation ignited fires would also be reduced.
Heat convection to the surrounding air, and thermal radiation are the primary modes of heat transport from the body.
Most of the thermal radiation emitted by objects near room temperature is infrared.
