Someone asked us later, "Didn't you wonder why no one came across you sooner?" Did I wonder? When you see your parents zipped up in black body bags on the Jellicoe Road like they're some kind of garbage, don't you know? Wonder dies. Melina Marchetta
a black body maintained at a constant temperature is a full radiator at that temperature because the radiation reaching and leaving it must be in equilibrium Source: Internet
A black-body with a temperature at or below room temperature would thus appear absolutely black, as it would not reflect any incident light nor would it emit enough radiation at visible wavelengths for our eyes to detect. Source: Internet
A black-body will also absorb the maximum possible incident radiation at any given wavelength. Source: Internet
According to theory, the Universe approximately a second after its formation was a near-ideal black body in thermal equilibrium at a temperature above 10 10 K. The temperature decreased as the Universe expanded and the matter and radiation in it cooled. Source: Internet
Effective Temperature of the Earth Similarly we can calculate the effective temperature of the Earth T ⊕ by equating the energy received from the Sun and the energy radiated by the Earth, under the black-body approximation. Source: Internet
