Stefan-boltzmann law of radiation equation
網頁Now we will use the Stefan-Boltzmann law to obtain the Area : We know that : P = εσAT^4 and σ is the Stefan-Boltzmann constant, which has a value of 5,67 × 10^-8 W/m^2K^4. So we have : A = P / (εσT^4) 網頁The law was discovered experimentally by Jožef Stefan (1835-1893) in 1879 and derived theoretically, using thermodynamics, by Ludwig Boltzmann (1844-1906) in 1884. Boltzmann treated a certain ideal heat engine with the light as a working matter instead of the gas. This law is the only physical law of nature named after a Slovene physicist.

http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/stefan.html 網頁Stefan-Boltzmann Law states that the energy per unit area that a blackbody emits increases as the temperature of the blackbody increases. Total emitted radiation is calculated by: Lastly, Wien's Displacement Law describes the relationship between the wavelength of emitted radiation and the temperature of the object.
網頁The Stefan-Boltzmann law relates the heat flow rate emitted or absorbed from an object to its temperature (and surface area and darkness).
