The photon radiated from hydrogen corresponding to a line of the Lyman series is absorbed by a hydrogen-like atom in an excited state. As a result, the hydrogen-like atom makes a transition to the nth orbit. What can be inferred from this?
1) The energy of the photon absorbed is equal to the energy difference between the nth and initial orbits.
2) The energy of the photon absorbed is greater than the energy difference between the nth and initial orbits.
3) The energy of the photon absorbed is less than the energy difference between the nth and initial orbits.
4) The energy of the photon absorbed is equal to the energy of the photon radiated in the Lyman series.
