Question

A hydrogen atom in an excited state emits a Balmer beta photon followed by a Lyman alpha photon. The electron decay from: the first excited state to the ground state, the second excited state to the ground state, the third excited state to the first excited state to the ground state, the third excited state to the second excited state to the ground state, or the third excited state to the second excited state to the first excited state to the ground state.
