Dark line absorption spectrum
WebAbsorption lines are usually seen as dark lines, or lines of reduced intensity, on a continuous spectrum. This is seen in the spectra of stars, where gas (mostly hydrogen) … WebSep 7, 2024 · If the gas is viewed at an angle away from the source of the continuous spectrum, a pattern of bright spectral lines (called emission lines) is seen against an other-wise dark background. As the radiation …

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. WebVerified questions. (a) Determine the mass of a gold foil that is 0.010 cm thick and whose area is 1 \mathrm {cm} \times 1 \mathrm {cm} 1cm×1cm.
