Answer:
the two lines observed correspond to Hydrogen and Helium
Explanation:
One of the great principles of atomic physics is that the emission and absorption lines of atoms are the same, in addition, each different element has a series of characteristic lines with which we can identify it.
Bohr's atomic model allows to fully explain the spectrum of lines and absorption of Hydrogen, in this case the line
λ = 656 nm
corresponds to a hydrogen trasition of the Balmer series from state n = 3 to state n = 2
The other line identified λ = 587 nm does not correspond to any hydrogen line and neither to heavy element lines, so this line when it was discovered was assigned to a new element, which was called Helium. This line is explained this element was assigned an atomic number (charge) of +2 and a mass of + 4 u, specifically it is a transition from level n = 3 to level n = 2
therefore the two lines observed correspond to Hydrogen and Helium
Answer:
Thus, astronomers can identify what kinds of stuff are in stars from the lines they find in the star's spectrum. This type of study is called spectroscopy. ... From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star.
