Fraunhofer spectra lines
In physics and optics, the Fraunhofer lines are a set of spectral absorption lines named after the German physicist Joseph von Fraunhofer (1787–1826). The lines were originally observed as dark features (absorption lines) in the optical spectrum of the Sun (white light) . See more In 1802, the English chemist William Hyde Wollaston was the first person to note the appearance of a number of dark features in the solar spectrum. In 1814, Fraunhofer independently rediscovered the lines and began to … See more 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 … See more • Myles W.

Fortunately, the H-atom spectral lines are well characterized in terms of frequency and intensity, allowing them to be distinguished from instrumental artifacts. dr gebeck orthodontistWebThe 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. dr gebrail wilmington ncWebThe article was published on 1954-02-01.
