question

(a) how is the stability of hydrogen atom in bohr model explained by de broglie's hypothesis?
(b) a hydrogen atom initially in the ground state absorbs a photon which excites it to n = 4 level. when it gets de-excited, find the maximum number of lines which are emitted by the atom. identify the series to which these lines belong. which of them has the shortest wavelength?
