Web9 jun. 2024 · The photosphere of the sun does produce an emission spectrum (a Planck spectrum according to its temperature of about 6000K). It is only that the atmosphere above the photosphere (the chromosphere) scatters light out of the line of sight at those frequencies where the scattering cross section is very high (i.e. at the atomic resonance … WebWhen the continuous spectrum is seen through a thinner gas cloud, the cloud’s atoms produce absorption lines in the continuous spectrum. When the excited cloud is seen without the continuous source behind it, its atoms produce emission lines. We can learn which types of atoms are in the gas cloud from the pattern of absorption or emission lines.

WebFor most elements, there is a certain temperature at which their emission and absorption lines are strongest. The lines you see in a star's spectrum act like thermometers. Some compounds, like titanium oxide, only appear in the spectra of very cool stars. Others, like helium, appear only in the spectra of very hot stars. WebA 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. Spectral lines are often used to identify atoms and molecules.These "fingerprints" can be compared to the previously collected ones of …

WebThe Sun produces an absorption spectrum, with dark lines across its spectrum. Chemical elements in the Sun's corona absorb specific wavelengths of light so their electrons are excited to higher energy levels. Emission takes place equally in every direction, with the result that the intensity of light in the Earth's direction is much reduced.
