Radiation Rate Equation

Reference from the original Physics I textbook.

Radiation Rate Equation

$P_{r a d i a t i o n} = σ ϵ A T_{o b j e c t}^{4}$

$P_{r a d i a t i o n} = Radiation Rate (Watt)$
$ϵ = Emissivity$
$A = Area (m^{2})$
$σ = Stephan Boltzman Constant (5.6704 \times 10^{- 8} {W/m}^{2} K^{4})$
$T = Temperature of Object (K)$

Thermal radiation
Thermal radiation is electromagnetic energy emitted by matter because of its temperature. It can transfer energy through a vacuum, and net radiative transfer between ordinary bodies is from hotter to cooler. For example, sunlight warming a surface does not need air to carry the energy across space.
