can be calculated using the following formula:

1/ λ = R (1/n2f - 1/n2i)

Where nf and ni are integers that can have values nf = 1, 2, 3, . . . , ∞ and ni = nf + 1, nf + 2, nf + 3, . . . , ∞. Which of the following sets of integers give the wavelength of a line in the Balmer series? (Note: more than one answer may be correct)
ni = 2 nf = 1
ni = 6 nf = 2
ni = 3 nf = 1
ni = 5 nf = 3
ni = 9 nf = 2

This sounds like homework. If so you should use the homework template. It's against PF rules for us to just give you the answer. What do you know about the hydrogen spectrum? What is the Balmer series?

Balmer series are comprised of transitions that end in the ##n_{f}=2##. Both answers with this criteria are correct.
Hope this helps.
Please read the PF rules.

Please read the PF rules.
Apologies. Should I remove the answer?
