Question

For a hydrogen-like atom, classify these electron transitions by whether they result in the absorption or emission of light: n=3 to n=5, n=1 to n=3, n=3 to n=2, n=2 to n=1? Ignoring the sign, which transition was associated with the greatest energy change?

Answer 1

The problem ask to provide among the following transition that states the where the transition is absorption or a emission and the answer are the following:
1 absorption
2 absorption
3 emission
4 emission
