Part of Speech

Noun

Phonetic Transcription

/ˈæŋɡstrəʊm ˈjuːnɪt/

Meaning and Usage

The "Angstroem unit" (often spelled "angstrom," symbol: Å) is a unit of length equal to one ten-billionth of a meter (1 Å = 10⁻¹⁰ m). It is commonly used in the fields of physics and chemistry to measure atomic, molecular, and crystal dimensions, especially in the context of wavelengths of light and X-rays.

The term is used primarily in scientific contexts, particularly in discussions involving atomic structures, spectroscopy, and materials science.

Frequency of Use

The Angstroem unit is more frequently used in written scientific literature than in oral speech, typically in research papers, textbooks, and technical articles.

Example Sentences

1. The wavelength of visible light ranges from about 4000 to 7000 angstroem units.

2. Длина волны видимого света варьируется от около 4000 до 7000 ангстремов.

3. Scientists have discovered molecules that emit light with a wavelength of 500 angstroem units.

4. Ученые обнаружили молекулы, которые излучают свет с длиной волны 500 ангстремов.

5. The crystal lattice dimensions were measured in angstroem units to ensure accuracy.

6. Размеры кристаллической решетки измерялись в ангстремах для обеспечения точности.

Idiomatic Expressions

While the term "Angstroem unit" itself is not commonly featured in idiomatic expressions, it does appear in scientific contexts. Here are some sentences showcasing how "angstrom" is incorporated in scientific discourse:

1. When exploring the atomic world, even a single angstrom can make a significant difference in measurement.

2. При исследовании атомного мира даже один ангстром может существенно повлиять на измерение.

3. The gap between molecules can be as small as a few angstroms, indicating close interactions.

4. Просвет между молекулами может составлять всего несколько ангстремов, указывая на близкие взаимодействия.

5. Understanding the structure of proteins at the angstrom level has advanced drug design significantly.

6. Понимание структуры белков на уровне ангстремов значительно продвинуло разработку лекарств.

Etymology

The term "angstrom" is named after the Swedish physicist Anders Jonas Ångström (1814-1874), who contributed significantly to the field of spectroscopy. The unit was adopted in 1868, reflecting the scale of the atomic and molecular dimensions that Ångström explored in his research.

Synonyms and Antonyms

Synonyms: - Ångström (symbol: Å)

Antonyms: - There are no direct antonyms for angstrom, as it is a specific measurement unit, but in a different context, one might refer to larger units of length such as micrometers (µm) or millimeters (mm) as being on a larger scale.
