Spectral lines

What is Spectral Lines?

One of a series of linear images formed by a spectrograph or similar instrument and corresponding to a narrow portion of the spectrum of the radiation emitted or absorbed by a particular source.

Spectral line shape describes the form of a feature, observed in spectroscopy, corresponding to an energy change in an atom, molecule or ion.

Spectral line is a dark or bright line in an otherwise continuous spectrum caused by absorption or emission of light. Spectral lines are often used to identify atoms and molecules.

How is light measured/detected?

A spectrograph is an instrument that separates light by its wavelengths and records this data. A spectrograph typically has a multi-channel detector system or camera that detects and records the spectrum of light.

The process of using a spectrometer to take a spectrograph.
