Spectroscopy - Types of electromagnetic-radiation sources

WebA spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from the emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. WebSpectral bands are parts of the electromagnetic spectrum of specific wavelengths, which can be filtered by a standard filter. In nuclear physics, spectral bands are referred to the emission of polyatomic systems, including condensed materials, large molecules, etc. Each spectral line corresponds to one level in the atom splits in the molecules.
