How are different spectral lines explained by Bohr's theory? 

The electronic structure of the atom that is correctly explained by Bohr’s theory in the following is ………..

Bohr.s theory explains that when Hydrogen-like particles are excited, their electrons are shifted higher energy orbits. As such a state of atom is not stable, electrons return to lower energy orbits releasing quantum of energy. Thus different spectral lines are formed. The wave number of spectral line is given by bar(v) = (2pi^(2)me^(4)z^(2))/(c h^(3))[(1)/(n_(1)^(2)-(1)/(n_(2)^(2)))] For a hydrogen -like particle, ionization energy is 122.4 eV. Then what is the wave number of series limit spectral line of the particle of paschen seres (R = rydberg.s constant)

What is the wave number of the spectral line emitted when electron falls from this level to the next lower level

Ionization potential of hydrogen atom is 13.6 eV hydrogen atoms in the ground state are excited by monochromatic radiation of photo energy 12.1 eV. According to Bohr's theorgy, the spectral lines emitted by hydrogen will be
