[edit] Summary

Description
English: Graph of a function of total emitted energy of a black body j^{\star} proporational to the fourth power of its thermodynamic temeprature T\, according to the Stefan–Boltzmann law. In turquoise colour is a total energy according to the Wien approximation, equals j^{\star} / \zeta(4) \approx 0.923938 j^{\star} .
Slovenščina: Graf funkcije odvisnosti gostote izsevanega energijskega toka črnega telesa j^{\star} od termodinamične temperature T\, po Stefan-Boltzmannovem zakonu. Turkizna barva je gostota energijskega toka po Wienovem približku, enaka j^{\star} / \zeta(4) \approx 0,923938 j^{\star} .
