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.

**Dr Russ**, Monday, February 16, 2009 at 3:47amThe 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.
