Flux density can be expressed in either frequency or wavelength space.

In wavelength space:

$ F _\lambda = \frac {\Delta E}{\Delta t \Delta A \Delta \lambda} $

In frequency space:

$ F _\nu = \frac {\Delta E}{\Delta t \Delta A \Delta \nu} $

Converting from wavelength to frequency spaceEdit

$ F _\nu = F _\lambda \frac {\Delta \lambda}{\Delta \nu} $
