The energy density of a black body between λ and λ + d λ is the energy E=hc /λ of a mode times the density of states for photons, times the probability that the mode is occupied. This is Planck's famous formula for the energy density of a black body. u (λ) [J m -4 ] 0.25. 0.50.
Black-body radiation has a characteristic, continuous frequency spectrum that depends only on the body's temperature, called the Planck spectrum or Planck's law. The spectrum is peaked at a characteristic frequency that shifts to higher frequencies with increasing temperature, and at room temperature most of the emission is in the infrared region of the electromagnetic spectrum. As the temp… Weba small amount of this emitted radiation may escape to compensate for the radiation that entered through the hole. Stars are also approximate black body radiators.
