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.
Fathom
A fathom is a unit of length equal to 6 feet, used especially for measuring the depth of water.
History/Origin
The term "fathom" comes from the Old English word "fæthm," meaning "outstretched arms," as the distance was originally the span of a man's outstretched arms.
Current Use
The fathom is still used in nautical applications, especially in the United States, to measure water depth. It is also used in commercial fishing to measure the length of lines.
