The observed wavelengths of the hydrogen spectrum

AI Thread Summary
The discussion focuses on calculating the observed wavelengths of the hydrogen spectrum using the formula 1/λ = R (1/n²f - 1/n²i). It identifies that the Balmer series consists of transitions ending in the nf = 2 state. Participants clarify that multiple sets of integers can yield valid wavelengths for the Balmer series. The conversation also emphasizes adherence to forum rules regarding homework help. Overall, the key takeaway is the importance of understanding the Balmer series and the correct application of the formula.

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.

Apologies. Should I remove the answer?
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
