Angstrom, Anders

Anders Jonas Angstrom was one of the founders of the science of spectroscopy. In the 1860s, he found hydrogen and other elements in the spectrum of the sun. A non-SI unit of length equal to 0.1 nm is named for him. 

Angstrom unit The unit of length commonly used in reporting the results of crystal structure analyses. 1 A = 10 cm. It is named after Anders Jonas Angstrom, a spectroscopist from Upsala, Sweden. 

The unit of length used in describing molecules and crystals is the Angstrom (symbol A), named in honor of the Swedish physicist Anders Jonas Angstrom (1814-1874). One centimeter is 100,000,000 A, and one inch is about 254,000,000 A. 

Angstrdm, Anders Jonas (1814-74) Swedish astronomer and physicist who became professor of physics at the U niversity of Uppsala from 1858 until his death. He worked mainly with emission spectra, demonstrating the presence of hydrogen in the sun. He also worked out the wavelengths of Fraunhofer lines. Since 1905 spectral wavelengths have been expressed in angstroms.

Since 1997 different scientific institutions at Uppsala University have joined in a center for education and research within fields connected to materials science. The laboratory is named after Anders Johan Angstrom (Figures 10.9 and 10.10) whose achievements were described above, and also after his son Knut Angstrom, also professor in Uppsala. The son Knut devoted a great part of his research to the radiation from the sun [10.10].

The SI unit for frequency, s , is the hertz (Hz), and the basic SI wavelength unit is the meter (m). Because many types of electromagnetic radiation have very short wavelengths, however, smaller units, including those listed below, are also used. The angstrom, named for the Swedish physicist Anders Angstrom (1814 1874), is not an SI unit.
