How Can The Energy Levels Of The Atom Be Determined By Measuring The Light Emitted From An Atom?

When an atom loses energy, it falls from a higher energy state to a lower energy
state. The frequency of the emitted light, observed in an element’s line-emission
spectrum, may be measured. The energy of each transition is calculated using the
equation E _ hv, where v is the frequency of each of the lines in the element’s line emission
spectrum. From the analysis of these results, the energy levels of an atom
atom of each element may be determined.
