The S ∝ ν - S - radiant Flux.
- ν - frequency.
- α - Spectral Index.
Confusingly, sometimes the term is used to mean the negative of this exponent, or equivalently, the analogous exponent of the Wavelength. In cases where the radiant flux by frequency is not a power law, it can be said that the spectral index varies by frequency. The concept seems less useful in this case. EMR,measure)Referenced by:
