Wikipedia article on the Fraunhofer lines.
The Fraunhofer lines are typical spectral absorption lines. .
The sun's spectrum with Fraunhofer lines.
In the Sun, Fraunhofer lines are a result of gas in the photosphere, the outer region of the sun.
Those are now called Fraunhofer lines.
The major Fraunhofer lines, and the elements they are associated with, are shown in the following table.
Projection of the solar spectrum with the Fraunhofer lines.
The major Fraunhofer lines, and the elements with which they are associated, appear in the following table.
The lines are called fraunhofer lines.
Joseph Fraunhofer(1787-1826) was a German physicist who first studied the Sun's spectra(these dark lines are now called Fraunhofer lines).
In 1854 Stokes theorised an explanation of the Fraunhofer lines in the solar spectrum.
They deduced that the Fraunhofer lines in the solar spectrum were caused by the absorption of specific colours of light in the outer layers of the Sun.
Spectra from the Sun including fraunhofer lines.
Because of their well defined wavelengths, Fraunhofer lines are often used to characterize the refractive index and dispersion properties of optical materials.
These lines are now called Fraunhofer lines.
The major Fraunhofer lines, and the elements they are associated with, are shown in the following table: The Fraunhofer C, F, G', and h lines correspond to the alpha, beta, gamma and delta lines of the Balmer series of emission lines of the hydrogen atom.
These lines are now known as the Fraunhofer lines.
Their studies also made it possible to explain the Fraunhofer lines and thus lay one of the most important foundations for modern astronomy.
He applied his techniques to the Sun,explaining Fraunhofer lines.
About 45 years later Kirchhoff andBunsen noticed that several Fraunhofer lines coincide with characteristic emission lines identified in the spectra of heated elements.
The absorption lines that we observe in the solar spectrum have a name: Fraunhofer lines.
In 1871, optical redshift was confirmed when the phenomenon was observed in Fraunhofer lines using solar rotation, about 0.1 Å in the red.
A high-resolution version of the solar spectrum,showing a great multitude of Fraunhofer lines.
On October 20 of the same year, English astronomer Norman Lockyer observed a yellow line in the solar spectrum,which he named the D3 Fraunhofer line because it was near the known D1 and D2 lines of sodium.
In 1814 in Germany, Josef Von Fraunhofer discovered dark lines in the Sun's spectrum.
The first evidence of quantization in atoms was the observation of spectral lines in light from the sun in the early 1800s by Joseph von Fraunhofer and William Hyde Wollaston.
Fraunhofer had observed bright lines in the spectrum produced by flames and noted that they appeared at similar frequencies to certain dark lines in the spectrum of the sun.
And the secret message? Those black vertical lines in Fraunhofer's spectrum?
The Fraunhofer letters are now rarely used for those lines. .
Fraunhofer's lines are the atomic signatures of the elements writ large across the cosmos.
