Quantum Mechanics
1011304Quantum MechanicsBohr's theory was fairly successful in describing the spectrum of hydrogen, but it did not explain the varying intensity of different spectral lines, nor did it adequately describe the spectrum of heavier atoms. Further, it did not explain the fact that under high resolution, some lines were found to be doublets. Sommerfeld showed that including elliptical orbits in Bohr's theory helped explain how the periodic table of elements was determined, but there was still no clear basis for some of Bohr's assumptions. More radical ideas were called for. The early 1920s was the time of another great leap forward in our understanding of nature. The theory that evolved is called quantum mechanics.
