An electron ina hydrogen atom undergoes a transition from an orbit with quantum number `n_(i) ` to another with quantum number `n_(f)` . `V_(i)` and `V_(f)` are respectively the initial and final potential energies of the electron. If `( V_(i))/( V_(f)) = 6.25`, then the smallest possible `n_(f ) ` is

Electron in a hydrogen atom undergoes transition from n_1 to n_2 , where n_1 and n_2 are the principal quantum numbers of two given states. According to Bohr's theory , if the time period of the electron in the initial state be eight times that in the final state , the possible values of n_1 and n_2 will be, respectively

Using Bohr's postulates, derive the expression for the frequency of radiation emitted when electron in hydrogen atom undergoes transition from higher energy state (quantum number n_(i) ) to the lower state, ( n_(f)) . When electron in hydrogen atom jumps from energy state n_(i) = 4 to n_(f) = 3, 2, 1 , identify the spectral series to which the emission lines belong.
