Anders Jonas Ångström (Swedish: [ˈânːdɛʂ ˈjûːnas ˈɔ̂ŋːstrœm]; 13 August 1814 – 21 June 1874) was a Swedish physicist and one of the founders of the science of spectroscopy. [ 1 ] Ångström is also well known for his studies of astrophysics , heat transfer , terrestrial magnetism , and the aurora borealis .
Anders Knutsson Ångström (1888 – 1981) was a Swedish physicist and meteorologist who was known primarily for his contributions to the field of atmospheric radiation. However, his scientific interests encompassed many diverse topics. [1] He was the son of physicist Knut Ångström. He graduated with a BS from the University of Upsala in 1909 ...
Portrait of Anders Ångström [15]. In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight, in which he expressed the wavelengths of electromagnetic radiation in the electromagnetic spectrum in multiples of one ten-millionth of a millimetre (or 10 −7 mm.) [16] [17] Ångström's chart and table of wavelengths in the solar spectrum became widely used in ...
Knut Johan Ångström (12 January 1857 – 4 March 1910) was a Swedish physicist. He was the son of physicist Anders Jonas Ångström and studied in Uppsala from 1877 to 1884, when he received his licentiat -degree, before going for a short time to the University of Strassburg ( Strasbourg ) to study with August Kundt .
The Uppsala Astronomical Observatory (UAO), Astronomiska observatoriet i Uppsala) is the oldest astronomical observatory in Sweden.It was founded in 1741, though there was a professorial chair of astronomy at the University of Uppsala from 1593 and the university archives include lecture notes in astronomy from the 1480s.
In 1929, the Swedish physicist Anders K. Ångström found that the optical thickness of an aerosol depends on the wavelength of light according to the power law = where is the optical thickness at wavelength , and is the optical thickness at the reference wavelength .
The airglow phenomenon was first identified in 1868 by Swedish physicist Anders Ångström.Since then, it has been studied in the laboratory, and various chemical reactions have been observed to emit electromagnetic energy as part of the process.
The facility is named after Swedish physicist Anders Jonas Ångström and his son Knut Ångström, both of whom were professors at Uppsala University in the 19th century. [3] It was first inaugurated in 1997, [4] at Polacksbacken , next to a site that historically served the purpose of training the Uppland Regiment from 1680–1912. This site ...
