Question

The energy levels of a hypothetical one-electron atom system are given by E n = - 16 n 2 eV , where n = 1 , 2 , 3 , … … . The wavelength of emitted photon corresponding to the transition from first excited level to ground level is about

TestHub · Accepted Answer

Given, E n = - 16 n 2 eV According to the question, E 1 = - 16 eV E 2 = - 16 ( 2 ) 2 eV = - 16 4 eV = - 4 eV We know that, λ = 12420 Δ E λ = 12420 | E 2 - E 1 | λ = 12420 | - 4 - - 16 | λ = 12420 12 λ = 1035 Å
