Blackbody planck function
In physics, Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T, when there is no net flow of matter or energy between the body and its environment. At the end of the 19th century, physicists were unable to explain … See more Every physical body spontaneously and continuously emits electromagnetic radiation and the spectral radiance of a body, Bν, describes the spectral emissive power per unit area, per unit solid angle, per unit frequency … See more Planck's law describes the unique and characteristic spectral distribution for electromagnetic radiation in thermodynamic … See more Consider a cube of side L with conducting walls filled with electromagnetic radiation in thermal equilibrium at temperature T. If there is a small hole in one of the walls, the radiation … See more A black-body is an idealised object which absorbs and emits all radiation frequencies.

This "Planck function" can be expressed in two ways: energy emitted per unit area per unit time per unit wavelength.
WebMar 5, 2024 · Integration of Planck's equation to arrive at Stefan's law is a bit more tricky. It should be clear that ∫ 0 ∞ M λ d λ = ∫ 0 ∞ M ν d ν, and therefore I choose to integrate the easier of the functions, namely M ν. To integrate M λ, the first thing we would do anyway would be to make the substitution ν = c / λ. Planck's equation ...
