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.
Decimeter
A decimeter is a unit of length in the metric system, equal to one-tenth of a meter.
History/Origin
The prefix "deci-" comes from the Latin word "decimus," meaning tenth. The decimeter was part of the original metric system adopted in France in 1795.
Current Use
The decimeter is not as commonly used in everyday life as other metric units like the centimeter or meter, but it is sometimes used in technical and scientific contexts.
