(a) When a hydrogen atom absorbs a photon of light, an electron is excited to an orbit that has a higher energy and larger value of n. (b) Images of the emission and absorption spectra of hydrogen are shown here. Web6. Sommerfeld (in 1916) expanded on Bohr’s ideas by introducing elliptical orbits into Bohr’s model. Sommerfeld’s improvement allowed the Bohr model to explain the splitting of the Balmer lines when the hydrogen atom was in an electric field.
