Stefan-Boltzmann law
Definitions
Astronomy
- (written as Stefan-Boltzmann Law)Rule connecting the peak frequency of radiation from a black body source with the fourth power of its temperature. The Stefan-Boltzmann Constant links the two and has a value of 5.69 x 10-8 Watts per square metre per Kelvin-4.
Electronics
- A law stating that the energy radiated by a blackbody per second per unit area is proportional to the fourth power of its absolute temperature.
