What primary method is utilized to confirm the elemental abundance ratios within nebulae spectra?
Answer
Spectroscopy
Spectroscopy is the fundamental technique employed by astronomers to confirm the relative abundance of elements present in a nebula. This method involves analyzing the light that is either emitted by or passes through the nebula. Atoms absorb or emit light at specific, unique wavelengths corresponding to the energy transitions of their electrons. By precisely measuring the strength of these spectral lines, scientists can accurately determine the relative quantities of hydrogen, helium, and heavier elements present in the cosmic gas.
