THE solar radiation spectrum does not normally extend ... assuming that the sun behaves as a perfect black-body radiator at a temperature of 6,000° K.

A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has ...

Invisible heat rays are only different from light rays in their period of oscillation or wavelength.” A black body not only emits radiation at a particular wavelength, but over the entire wavelength ...

While a tungsten lightbulb's filament is much warmer than its surroundings, the law defining blackbody radiation—Planck's law—offers a good approximation of the spectrum of photons it sends out.

However, traditional blackbody radiation, due to its inherent characteristics, such as its non-directional, incoherent, broad-spectrum, and unpolarized nature, results in energy exchange between ...
