Ångström definition of Ångström in the Free Online Encyclopedia.

angstrom (ăng`strəm), abbr. Å, unit of length equal to 10⁻¹⁰ meter meter, 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

(0.0000000001 meter); it is used to measure the wavelengths of visible light and of other forms of electromagnetic radiation electromagnetic 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

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.
