Han började sin skolning i Härnösand, och senare - 1833 - som student vid Uppsala universitet. His most important work was concerned with heat conduction and spectroscopy. "Observations on Certain Lines of the Solar Spectrum". Anders Ångström. August 1814 in Lögdö bruk, Gemeinde Timrå; † 21. "...Anders Jonas Ångström (13 August 1814 – 21 June 1874) was a Swedish physicist and one of the founders of the science of spectroscopy. Anders Jonas Ångström (Aussprache: [.mw-parser-output .IPA a{text-decoration:none}ˌanːdəʂ ˈɔŋːstɾœm]; * 13. Anders Jonas Ångström Swedish physicist. Er war auch Mitglied der Königlich Schwedischen Akademie der Wissenschaften (seit 1850), der Königlichen Physiographischen Gesellschaft in Lund (seit 1866), der Preußischen Akademie der Wissenschaften (seit 1867), der Royal Society (seit 1870), der Königlich Dänischen Akademie der Wissenschaften (seit 1873) und der Académie des Sciences (ebenfalls seit 1873). Han bestämde våglängderna för ca 1000 absorbtionslinjer och använde då meterskalan. fregatten Eugenies resa omkring jorden, delen III: Fysik (1858—1874). forgotten. Namngivit Ångströmlaboratoriet i Uppsala. Vidare visade han att en kemisk förenings spektrum innehåller linjer som är karakteristiska för dess beståndsdelar. Geni requires JavaScript! His combination of the spectroscope with photography for the study of the Solar System resulted in proving that the Sun's atmosphere contains hydrogen, among other elements (1862), and in 1868 he published his great map of the normal solar spectrum in Recherches sur le spectre solaire, including detailed measurements of more than 1000 spectral lines, which long remained authoritative in questions of wavelength, although his measurements were inexact by one part in 7000 or 8000, owing to the metre he used as a standard being slightly too short. Ångström visade bland annat att en elektrisk gnista ger upphov till spektrallinjer som är karakteristiska dels för metallen i elektroderna, dels för den omgivande gasen. Anders Jonas Ångström (n. 13 august 1814 – d. 21 iunie 1874) a fost un fizician și astronom suedez, unul dintre inventatorii spectroscopiei. Docent i experimentiell fysik vid Uppsala universitet 1840, astronomie observator 1843, professor i fysik 1858. Anders Jonas Ångström was a pioneer in the field of spectroscopy, and he is also well known for his studies of astrophysics, heat transfer, terrestrial magnetism, and the aurora borealis. originated and has been relegated to the status of a “non-SI unit,” it still Juni 1874 in Uppsala) war ein schwedischer Astronom und Physiker sowie Mitbegründer der Astrospektroskopie.Nach ihm ist die ein zehnmillionstel Millimeter betragende Maßeinheit für Wellenlängen von elektromagnetischer Strahlung benannt.
In 1858, he succeeded Adolph Ferdinand Svanberg in the chair of physics at Uppsala. His greatest work was with the solar spectrum, and it is from this work that his fame as the
Optiska undersökningar kom att bli fundamental för spektralanalysen, och är ett av de första arbetena inom spektroskopin.

Životopis. Han var en av grundarna till spektroskopin, och enheten ångström (1 Å = 10^-10 meter=0,1nm) är uppkallad efter honom. --------------------------------------------. svéd fizikus, a színképelemzés (spektroszkópia) egyik megalapítója, az ångström hosszúságegység névadója.. Az uppsalai egyetemen végezte tanulmányait, 1839-ben egyetemi magántanár majd 1858-tól a fizikai tanszék vezetője lett, 1843-töl az uppsalai obszervatórium munkatársa. Bland skrifterna: De theoria lucis calorisque (1839), Försök till en mathematisk theorie för det thermometriska värmet (1848—1854); Optiska undersökningar (1855), Ny method att bestämma kroppars ledningsförmåga för värme (1861), Spectre normal du soleil (med Atlas, 1868); Ueber das Spektrum des Nordlichts (1874). namesake of the ångström comes.
Internationellt känd blev han för sina omfattande mätningar av Fraunhoferlinjerna i solspektrum. Anders Jonas Ångström (Lögdö, 13. kolovoza 1814. 1839 wurde er promoviert und unterrichtete Physik an der Universität, ab 1858 bis zu seinem Tod auch als Professor. In 1868 he published a book containing a map of the entire visible solar spectrum, Fysiker och astronom.
