Meaning and Usage

Fraunhofer lines are dark lines that appear in the spectrum of light emitted or absorbed by a substance, particularly in the spectra of stars and other celestial objects. These lines are caused by the absorption of specific wavelengths of light by various elements and compounds, allowing scientists to determine the composition and physical properties of distant stars and galaxies.

Fraunhofer lines are primarily used in scientific and astronomical contexts, making their occurrence more frequent in written texts (research papers, articles) rather than in oral communications. Their importance lies in spectroscopy, which is a technique to analyze light emitted or absorbed by matter.

Example Sentences

1. The study of Fraunhofer lines allows astronomers to identify the chemical composition of stars.

2. Исследование линий Фраунгофера позволяет астрономам определить химический состав звезд.

3. By analyzing the Fraunhofer lines, scientists can understand the temperatures and pressures in stellar atmospheres.

4. Анализируя линии Фраунгофера, ученые могут понять температуры и давления в атмосферах звезд.

5. The presence of certain Fraunhofer lines could indicate the existence of specific elements in the universe.

6. Наличие определенных линий Фраунгофера может указывать на существование конкретных элементов во Вселенной.

Idiomatic Expressions

Although "Fraunhofer lines" is a specific scientific term, it does not have widely recognized idiomatic expressions in colloquial English. However, the concept can be related to various expressions about "lines" or "spectrums," typically used in scientific discussions. Here are some sentences for illustrative purposes:

1. The spectrum of human experience is filled with bright and dark lines, much like the Fraunhofer lines in light.

2. Спектр человеческого опыта полон ярких и темных линий, как линии Фраунгофера в свете.

3. In art, the lines between reality and illusion can be as distinct as Fraunhofer lines in a spectrum.

4. В искусстве границы между реальностью и иллюзией могут быть такими же четкими, как линии Фраунгофера в спектре.

5. Just as Fraunhofer lines help us see the universe's makeup, our experiences shape the lines of our character.

6. Так же как линии Фраунгофера помогают нам увидеть состав вселенной, наш опыт формирует линии нашего характера.

Etymology

The term "Fraunhofer lines" is named after the German physicist Joseph von Fraunhofer, who first studied these absorption lines in the early 19th century. Fraunhofer's work laid the foundation for the field of spectroscopy.

Synonyms and Antonyms

Synonyms: - Absorption lines - Spectral lines

Antonyms: There are no direct antonyms for "Fraunhofer lines" as it is a specific term in spectroscopy. However, in the broader context of light and spectrum, one might consider terms related to not absorbing, such as "emission lines" (which occur when an element emits light at certain wavelengths).
