angstrom

(ăng`strəm), abbr. Å, unit of length equal to 10−10 metermeter,
abbr. m, fundamental unit of length in the metric system. The meter was originally defined as 1/10,000,000 of the distance between the equator and either pole; however, the original survey was inaccurate and the meter was later defined simply as the distance between two

 (0.0000000001 meter); it is used to measure the wavelengths of visible light and of other forms of electromagnetic radiationelectromagnetic radiation,
energy radiated in the form of a wave as a result of the motion of electric charges. A moving charge gives rise to a magnetic field, and if the motion is changing (accelerated), then the magnetic field varies and in turn produces an electric field.

, such as ultraviolet radiation and X rays. Scientists now prefer to use the nanometer (nm); 1 nm=10 Å. The angstrom is named in honor of Swedish physicist Anders J. Ångström.

angstrom

(ang -strŏm) Symbol: Å;. A unit of length equal to 10–10 meters. It was formerly used to specify interatomic distances.

angstrom

[′aŋ·strəm]
(mechanics)
A unit of length, 10-10 meter, used primarily to express wavelengths of optical spectra. Abbreviated A; Å. Also known as tenthmeter.

angstrom

A unit of length; used to express electromagnetic wavelengths; 1 Å = 10-10 meter = 1/10 nanometer. Abbr. Å.

angstrom

a unit of length equal to 10--10 metre, used principally to express the wavelengths of electromagnetic radiations. It is equivalent to 0.1 nanometre.

angstrom

A unit of measurement equal to .1 nanometer, which is approximately 1/250 millionth of an inch. Angstroms are used to measure the wavelengths of light and the elements in a chip. One nanometer is equal to 10 angstroms, and one micron is equal to 10,000 angstroms. The size of an atom is three to 10 angstroms.
