MCQ
Whenever a hydrogen atom emits a photon in the Balmer series
  • A
    It need not emit any more photon
  • B
    It may emit another photon in the Paschen series
  • ✓
    It must emit another photon in the Lyman series
  • D
    It may emit another photon in the Balmer series
✓

Answer

Correct option: C.
It must emit another photon in the Lyman series
c
(c)Since in spectral series of hydrogen atom, Lymen series lies lower Balmer series.
