Angstrom – Definition & Meaning

The angstrom is a unit of measurement used in the field of science to measure wavelengths of light and other electromagnetic radiation. It is a small unit of measurement, equal to one ten-billionth of a meter. Despite its small size, the angstrom plays an important role in the scientific community.

Definitions

An angstrom is defined as a unit of length equal to one ten-billionth of a meter. It is abbreviated as Å. The angstrom is commonly used to measure the size of atoms and molecules. It is also used to measure the wavelengths of light and other electromagnetic radiation.

Origin

The angstrom is named after the Swedish physicist Anders Jonas Ångström. He was a pioneer in the field of spectroscopy, which is the study of the interaction between matter and electromagnetic radiation. In 1868, Ångström was the first to use the unit of measurement that now bears his name.

Meaning in different dictionaries

In the Oxford English Dictionary, the angstrom is defined as “a unit of length equal to one ten-billionth of a meter, used especially to express wavelengths of electromagnetic radiation.” In Merriam-Webster, it is defined as “a unit of length equal to one ten-billionth of a meter, used especially to express wavelengths and interatomic distances.”
