• Atomic energy levelRelated: Excited atoms emit photons whose energies match gaps between their levels.

• Spectral resolutionRelated: Narrow emission lines provide common features for evaluating spectral resolution.

• Electronic transitionRelated: Emission lines identify photons produced by downward electronic transitions.

• Kirchhoff's laws of spectroscopyRelated: Hot, low-density gas produces bright spectral lines under the second rule.

• Norman LockyerRelated: Solar prominence emission lines made the helium feature visible for comparison.

• IndiumRelated: Indium’s bright blue spectral line gave the element its name and first identification.

• LuminescenceRelated: Its spectral pattern helps identify the emitting substance and its transitions.

• Stokes shiftRelated: Its emission band supplies the other side of the difference.

• Margaret Lindsay HugginsRelated: Emission patterns helped distinguish the spectra of nebulae from those of stars.
