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.
Rod
A rod, also known as a perch or pole, is a unit of length equal to 16.5 feet, or 5.5 yards.
History/Origin
The rod has been used as a unit of measurement in England since at least the 13th century. It was a convenient length for measuring land.
Current Use
The rod is now an archaic unit of measurement, though it may still be encountered in old land deeds.
