Genaral information on the "Spectral series of hydrogen (H2)"
The quantum leaps are explained on the basis of Bohr's theory of atomic structure. From the Lymann series to the Brackett series, it can be seen that the energy applied forces the hydrogen electrons to a higher energy level by a quantum leap. They remain at this level very briefly and, after about 10-8 s, they return to their initial or a lower level, emitting the excess energy in the form of photons (once again by a quantum leap)
