A spectral line is a discrete frequency or wavelength of light emitted or absorbed by an atom. It arises from a transition of an electron between different energy levels.

Spectral lines produced by electron transitions between discrete energy levels in an atom.
Description
Each spectral line corresponds to a specific difference in energy between two energy levels. When an electron transitions to a lower level, a photon is emitted; when it moves to a higher level, a photon is absorbed.
The set of spectral lines forms an atomic spectrum, which is characteristic of each element.
Properties
- discrete wavelengths or frequencies
- determined by energy level differences
- produced by transitions
