WebMar 20, 2024 · 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. The angstrom is also used to measure such quantities as atomic and molecular sizes (most elements … WebNov 22, 2024 · The diameter of an atom is on the order of 1 angstrom, so the unit is particularly handy when referring to the atomic and ionic radius or size of molecules and spacing between planes of atoms in crystals.
