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

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.

angstromA 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.
