--Absorption spectra occur when light is shined on a gas and certain wavelengths are absorbed by the gas, creating dark absorption lines (stars have these kind of spectra) --The wavelengths of the absorption lines for a given element are the same as those of its emission lines (Kirchoff’s law)

The important thing to know about absorption and emission lines is that every atom of a particular element will have the same pattern. of lines all the time. And the spacing of the lines is the same in both absorption and emission, only emission lines are added to the continuum, while absorption lines are subtracted. In . Part One

Sep 16, 2009 · Note that the dark lines in an absorption spectrum appear at exactly the same frequencies as the bright lines in the corresponding emission spectrum. The Absorption Spectrum of Hydrogen The Emission Spectrum of Hydrogen. What does this have to do with stars? If you look more closely at the Sun's spectrum, you will notice the presence of dark lines.

In addition, the locations (energies) at which absorption or emission lines occur can be used to “fingerprint” the star’s composition. The goal of this problem set is for you to understand that astronomers classify stars on the basis of two different criteria: (1) the intensity of one of the H absorption lines (called H-alpha, or H ), and ...

In the visible part of the solar spectrum there is virtually no gas absorption by the natural atmosphere, except a very small amount O3 < 0.06 by ozone, and a couple of narrow lines of oxygen absorption. As a result the key factors reducing the solar beam in cloud-free skies are …

Therefore, atomic emission absorption, and fluorescence spectra are made up of a limited number of narrow peaks, or lines. Electrothermal Atomization Electrothermal atomizers, which first appeared in 1970, generally provide enhanced sensitivity because the entire sample is atomized in a short period, and the average residence time of the atoms ...

There are two types of lines, basically at the same wavelengths (energies): emission and absorption lines. Those shown above are dark, meaning that light at that wavelength is being absorbed. Absorption lines occur when the energy kicks an electron to a higher energy orbital (thus it absorbs energy).
