Definition

change of radiant energy density with wavenumber, expressed by

w_{\tilde{ν}} = \frac{d w}{d \tilde{ν}}

where $w$ is radiant energy density (radiant energy density) as a function of wavenumber $\tilde{ν}$ (ISO 80000-3: Space and time)

variation de l'énergie rayonnante volumique en fonction du nombre d'onde, exprimée par
