B Hydrogen Transitions Quick Question

  1. Apr 25, 2017 #1
    Hello everyone!

    I have a question about the possible transitions for a hydrogen atom from an excited state back to the ground state.

    Lets say that a H atom is in the n = 4 excited state, what are the possible transitions back to n = 1?

    I thought the answer was:
    4 -> 3
    4 -> 2
    4 -> 1
    but then I guess we need to include:

    But the first and second possibilities you listed there don't end in n = 1. So yes, you have to include all "cascading" transitions.
