(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 interaction with atoms, and for EMR wavelengths in the range of near infrared and shorter.
