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

The wavelength of one line in the visible region o fthe atmoic spectrum of hydrogen is 6.5xx10^(-7)m . This radiation is emitted when electron in a hydrogen atom goes from a high enegry state to a lower energy state. Calculate the difference in enegry between the two states. Strategy: According to the Bohr frequency rule, if the electron jumps from one orbit whose quantum number is n_(1) to a second orbit whose quantum number is n_(f) , the difference in enegry (DeltaE) is related to the frequency (v) of the radiation which in turn is related to the wavelength (lambda) : ? DeltaE = hv and v = (c)/(lambda) Thus, DeltaE = (hc)/(lambda)
