presence of various gasses. when a single index of refraction in the material. The visible spectrum is produced.
Studying Fraunhofer lines helps to identify elements on the stars.
The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
Fraunhofer realised that some of these dark lines were at the same position in effect called the Zeeman effect can also cause splitting of the spectral lines.

hahaha boang ka cm8 oi.. kinsa ka? naka answer naka?
Discontinuous Spectra, Fraunhofer lines
absorption lines due to the thin outer layer above the photosphere
Joseph von Fraunhofer lived from 1787-1826. He became the director of a scientific institute in Germany. He made some of the best telescope lenses, which he was trained to do. He identified the dark absorption lines that are in the solar spectrum. These lines show scientists which chemical elements are in light.
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
No. You're thinking of Fraunhofer. A natural slip for English speakers.
The population of Fraunhofer Society is 18,000.
Fraunhofer Society was created in 1949.
