read the Earth science book you will find the answer
They represent elements in the outer layers of the star.
The dark lines represents the absorption of energy at that frequency, E=hf.
because they will have the same elements in the atmosphere...
The lines are at the same frequencies
No, it is named from the blue (indigo) lines in its spectrum.
The red end of the spectrum.
Absorption lines
because all of the different lines of a star's elements appear together i its spectrum, making the pattern different everytime
An emission spectrum depend on electrons transition in the atom of a chemical element; and elements are different.Absorption spectrum is based on the different absorption pics of different molecules, depending on the frequency of radiation.Spectral methods are largely used in analytical chemistry.
absorption lines! :)
Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum

The dark lines are absorption spectrum, the energy absorbed by Atoms in the atmosphere of the star. ================================ Fraunhofer's spectral lines.
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
The absorption lines in the infrared portion of the spectrum of a star that are produced by hydrogen are from the Balmer series. The Balmer series were discovered by Johann Balmer in 1885.
By looking at its emission spectrum and seing where the black lines are
