How did sommerfeld explain the fine sturcture of hydrogen spectrum ?

Answer»

SOLUTION :Sommerfeld suggested that the SUB-energy LEVELS or subshells associated with each main energy level are responsible for fine structure of hydrogen spectrum.These sub -energy levels or subshells EXIST due to the difference in the energies of the ELECTRONS revolving in different elliptical orbits belonging to the same main energy level.
