WebApr 10, 2024 · The radiation energy per unit time from a black body is proportional to the fourth power of the absolute temperature and can be expressed as the following formula. Radiate energy = (Stefan-Boltzmann constant) * (Temperature) 4. The equation is: J = σ T 4 J m-2 s-1. J - Energy radiated per unit area by a blackbody per unit time [Units: J m-2 s-1] WebBlackbody Radiation. All objects with a temperature above absolute zero (0 K, -273.15 o C) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or …
