Black body radiation |
In ideal case, all photons flying out
the black body are emited by only one atom, say a. The wall
of the black body is formed by n emiting atoms. What
distribution has radiation inside the black body, supposing
that the maximal frequency of any photon is m?

Nope- blackbody radiation is the term given to a spectral distribution
of photons in thermal equilibrium at a temeprature 'T'. It's
material-independent.
The wall
of the black body is formed by n emiting atoms. What
distribution has radiation inside the black body, supposing
that the maximal frequency of any photon is m?
The spatial distribution of electromagnetic energy in a cavity is a
fairly standard calculation.

Wow. Three sentences. Three errors. Perfect batting average.
