Kirchhoff's Laws

(Kirchhoff's Three Laws Of Spectroscopy)
(laws regarding the source of spectral lines)

Kirchhoff's Laws (Kirchhoff's Three Laws Of Spectroscopy) indicate the source of Spectral Lines.

  1. A hot solid, liquid, or dense gas produces a Continuous Spectrum.
  2. A hot thin gas produces Emission Lines.
  3. A continuous spectrum passing through a cold thin gas produces Absorption Lines.

The developer, physicist Gustav Kirchhoff, also devised other groups of laws, e.g., "Kirchhoff's Laws" of circuits.
