Explanation:
Detailed explanation-1: -angstrom (Å), unit of length, equal to 10−10 metre, or 0.1 nanometre. It is used chiefly in measuring wavelengths of light. (Visible light stretches from 4000 to 7000 Å.) It is named for the 19th-century Swedish physicist Anders Jonas Ångström.
Detailed explanation-2: -The angstrom (ångström) is a metric unit of length that is equal to 10 m. 1 angstrom is one ten-billionth of a meter 0.1 nanometre or 100 picometres.
