Light Year
A light-year is the distance that light travels in a vacuum in one Julian year.
History/Origin
The concept of the light-year as a unit of distance in astronomy emerged in the mid-19th century. The first recorded use of the term was in a German astronomical publication in 1851.
Current Use
The light-year is used to express distances to stars and other astronomical objects on a galactic and intergalactic scale, especially in popular science and non-specialist contexts.
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.
