| It follows, then, that any radiation emitted by the cavity radiator corresponds to the definition of blackbody radiation. |
|
| The term perfect blackbody applies to bodies that act as perfect radiators or absorbers of heat. |
|
| In 1893 Wien stated his displacement law of blackbody radiation spectra at different temperatures. |
|
| Soot, carbon black, platinum black, and carborundum are among the materials that come closest to a blackbody in the real world. |
|
| Moreover, we used the real IR emitter spectral emission obtained from out supplier to approximate the emission of the IR emitter instead of using the blackbody theory. |
|
| In these studies, a blackbody source was used at liquid nitrogen temperatures to test FIRAS performance, but not with its real bolometers in place. |
