Yes, four of the lines on the spectra line up. Note: The elements in a star's spectrum do not necessarily reflect what the star is made of. The absorption spectrum is mostly determined by the surface temperature of the star.
A key piece of evidence for the quantized electronic structure of an atom is the hydrogen spectrum. As soon as an electric discharge passes through a gaseous hydrogen molecule, the molecule's hydrogen atoms disintegrate. The energetically excited hydrogen atoms cause the emission of electromagnetic radiation, which is what happens. The hydrogen emission spectrum includes distinct frequency radiation. These radiation series have the names of the researchers who first identified them. The electron moves to a higher energy level, such as n = 1 or n = 2, when a hydrogen atom absorbs a photon, for instance. When a photon passes through an atom of hydrogen, the electron changes from one energy level to another, for instance, from n = 3 to n = 2. The transmission of light happens during this change from a higher level to a lower level. The spectrum contains wavelengths that represent the variations in these quantized energy levels due to the quantized energy levels of the atoms. For instance, the transition between n = 3 and n = 2 is shown by the line at 656 nm.
