This problem really bugs me and I did figure out the diagram but I cannot figure out the wavelength. Please help me with this problem.
The transitions of
i) n=2 to n=4
ii) n=3 to n=1
iii)n=5 to n=2
iv) n=3 to n=4
which corresponds to emission of radiation with the longest wavelength? Explain.

The levels are in the order
n=5
n=4
n=3
n=2
n=1
without knowing the spacing we know that n=1 to n=5 will have the highest energy and a transition between two adjacent levels will have a lower energy.
So what is the relationship between wavelength and energy? This will then tell you which transition it corresponds to.
