(unit of length 10-10 meters)

An Angstrom (Å) is a unit of length 10-10 meters long, or 1/10 of a Nanometer. Both are convenient units of length in atomic physics including the study of Electromagnetic Radiation (EMR) interaction with atoms, and for EMR Wavelengths in the range of Near Infrared (NIR) and shorter.
