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.
Exameter
An exameter is a unit of length in the metric system equal to 10^18 meters.
History/Origin
The prefix "exa-" for 10^18 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The exameter is used in astronomy to measure the vast distances between galaxies.
