Å.�� A.��Also called: angstrom unit.��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

Å�Բ��ٰ�ö��

Swedish physicist and astronomer who pioneered the use of the spectroscope in the analysis of radiation. By studying the spectrum of visible light given off by the Sun, Å�Բ��ٰ�ö�� discovered that there is hydrogen in the Sun's atmosphere. The angstrom unit of measurement is named for him.

angstrom

A unit of length equal to one hundred-millionth (10 ^{^- 10}) of a meter. It was once used to measure wavelengths of light and the diameters of atoms, but has now been mostly replaced by the nanometer.
