♦ Angstrom, Anders Jonas ♦ Wave Length
(ohng'strum) (1814-1874) Swedish physicist.
Born at Lodgo, Bruk; died at Uppsala. In 1862, he discovered the presence of hydrogen in the Sun, by inspecting the solar spectrum. He published a map of the spectrum, in 1868, locating the wavelength of nearly 100 lines. For these measurements he introduced a measuring unit, which has been named in his honor. The angstrom is a unit of wavelength equal to one-billionth of a meter (10-9 meter).
