A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
