The light which is produced in the core of the sun passes through layers of comparatively cold gas clouds on the surface of the sun. These clouds absorb some of the sun's light producing dark lines in the spectrum of the sun and sky. Two of the lines, called Fraunhofer C and I) lines after their discoverer, are found at about 656 nm and 587 nm, respectively. Looking at your atomic spectroscopy data, which elements that you examined would absorb at these wavelengths

Sagot :

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
