Category:Definitions/Stefan-Boltzmann Constant

This category contains definitions related to Stefan-Boltzmann Constant.

The Stefan-Boltzmann constant is the constant of proportion that defines the intensity of the thermal radiation emitted by a body in terms of that body's temperature:

$\sigma := \dfrac {2 \pi^5 k^4} {15 c^2 h^3}$

where:

$k$ is Boltzmann's constant

$c$ is the speed of light

$h$ is Planck's constant.
