Dark line absorption spectrum
WebSep 21, 2024 · The characteristic dark lines are mostly due to the absorption of light by elements that are present in the cooler outer part of the sun’s atmosphere; specific elements are indicated by the labels. ... This produces an absorption spectrum, which has dark lines in the same position as the bright lines in the emission spectrum of an element ... WebThe gaps (dark lines) in an absorption spectrum are formed because light of the specific energy (or wavelength, if you prefer) in the dark lines is absorbed by the atoms in a gas. This process is called photo-excitation.

A dark-line spectrum, or absorption spectrum, is exactly the opposite — instead of bright lines at each wavelength on a dark background, an absorption spectrum has dark lines at the corresponding wavelengths … birmingham glasses shopA spectral line may be observed either as an emission lineor an absorption line. Which type of line is observed depends on the type of material and its temperature relative to another emission source. An absorption line is produced when photons from a hot, broad spectrum source pass through a cooler material. See more A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. … See more Strong spectral lines in the visible part of the spectrum often have a unique Fraunhofer line designation, such as K for a line at 393.366 … See more Bands The phrase "spectral lines", when not qualified, usually refers to lines having wavelengths in the visible band of the full electromagnetic spectrum See more • Griem, Hans R.
