Ångström

The ångström or angstrom (symbol Å) (pronounced /ˈɔːŋstrəm/; Swedish: IPA: [ˈɔŋstrˈøm]) is an internationally recognized unit of length equal to 0.1 nanometre or 1 × 10 metres. It is named after Anders Jonas Ångström. Although accepted for use, it is not formally defined within the International System of Units (SI). The ångström is often used in the natural sciences for expressing the sizes of atoms, lengths of chemical bonds and the wavelengths... more

The ångström or angstrom (symbol Å) (pronounced /ˈɔːŋstrəm/; Swedish: IPA: [ˈɔŋstrˈøm]) is an internationally recognized unit of length equal to 0.1 nanometre or 1 × 10 metres. It is named after Anders Jonas Ångström. Although accepted for use, it is not formally defined within the International System of Units (SI). The ångström is often used in the natural sciences for expressing the sizes of atoms, lengths of chemical bonds and the wavelengths of electromagnetic radiation, and in technology for the dimensions of parts of integrated circuits. It is also commonly applied in structural biology. The ångström is named after the Swedish physicist Anders Jonas Ångström (1814–1874), one of the pioneers in the field of spectroscopy, who is known also for studies of astrophysics, heat transfer, terrestrial magnetism, and the aurora borealis. In 1868, Ångström created a chart of the spectrum of solar radiation that expresses the wavelength of electromagnetic radiation in the electromagnetic... less
