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.
Nanometer
A nanometer is a unit of length in the metric system, equal to one billionth of a meter.
History/Origin
The term “nanometer” gained prominence in the late 20th century with the advent of nanotechnology and the development of microscopes capable of observing objects at that scale.
Current Use
The nanometer is commonly used to express dimensions on an atomic and molecular scale. It is used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum and in the field of nanotechnology.
