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.
Centimeter
A centimeter is a unit of length in the metric system, equal to one-hundredth of a meter.
History/Origin
The prefix "centi-" comes from the Latin word "centum," meaning hundred. The centimeter was part of the original metric system established in France in 1795.
Current Use
The centimeter is a very common unit of measurement for everyday objects and is used in many fields, including science, engineering, and fashion.
