Sentences with phrase «of a blackbody»

Planck's blackbody radiation law characterizes the properties (spectral distribution, directionality, magnitude) of electromagnetic radiation emitted from a planar differential area on the surface of a blackbody at a known temperature.

Finally, we find that rotational temperatures are similar to, or slightly lower than, the expected temperature of blackbody grains located at the CO inner radius, in contrast to expectations of thermal decoupling between gas and dust.

and 1/2 of the blackbody exposed to a less then 3 Deg.

Earth's annual mean surface temperature of 15 °C is 33 °C higher as a result of the greenhouse effect than the mean temperature resulting from radiative equilibrium of a blackbody at the earth's mean distance from the sun.

Below that you are no longer at the shell of the blackbody but inside of the black body where radiant energy bounces around until it it finds a home in some spectrum that adds to the emissivity.

The peak of the blackbody emissions from Earth's surface, determined by a temperature which is comfortable for much of life, is very close to that massive CO2 absorption region around 667 per cm.

The Draper point, named after 19th century scientist John William Draper, is the approximate temperature (977 degrees Fahrenheit, 525 degrees Celsius) above which nearly all solid materials will begin to emit visible light (e.g. glow «red hot») as a result of blackbody radiation.

I have taken yet another attempt at writing up a description of why there must be limits to the greenhouse effect and why this limit is almost certainly that of a blackbody.
