These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun. \(1\). Line spectra are produced when electrons move from one ...

This limitation has led to long-standing assumptions and uncertainties regarding the precise ratio of Helium to Hydrogen (He/H) in the Sun's surface layer.
