Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
Femtometer
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
