| | |  Black body - Wien's displacement law: Encyclopedia II - Black body - DetailsIn the laboratory, the closest thing to black-body radiation is the radiation from a small hole entrance to a larger cavity. Any light entering the hole would have to reflect off the walls of the cavity multiple times before it escaped and is almost certain to be absorbed by the walls in the process, regardless of what they are made of or the wavelength of the radiation (as long as it is small compared to the hole). The hole then is a close approximation of a theoretical black body and if the cavity is heated, the spectrum of the hole's radi ...

Main article: Planck's law of black-body radiation
where
is the amount of energy per unit surface per unit time per unit solid angle emitted in the frequency range between ν and ν+dν;
is the temperature of the black body;
is Planck's constant;
is the speed of light; and

| | | | Black body - Wien's displacement law: Encyclopedia II - Black body - Temperature relation between a planet and its star Here is an application of black-body laws. It is a rough derivation that gives an order of magnitude answer. See p380-382 of Planetary Science, for further discussion.
Black body - Assumptions.
The surface temperature of a planet depends on a few factors:
Incident radiation (from the sun, for example)
The Albedo effect (the fraction of light a planet reflects)
The greenhouse effect (for planets with an atmosphere)
Energy generated inter ...
