Homework Statement
Find the wavelength of the sodium transition [tex]3p^{1},^{2}P -> 3s^{1},^{2}S[/tex]
Homework Equations
[tex]E_{n,l} = -\frac{hcR}{(n - d(n,l))^{2}}[/tex]
d(3,s) = 1.374
d(3,p) = 0.884
[tex]\lambda = \frac{\hbar c}{\Delta E}[/tex]
The Attempt at a Solution
Plugging the numbers in ain't even close. However, I've found another equation that works:
[tex]\frac{1}{\lambda} = -R[\frac{1}{(n_{i} - d_{i}(n,l))^{2}} - \frac{1}{(n_{f} - d_{f}(n,l))^{2}}][/tex]
but since E is proportional to [tex]\hbar[/tex] and the RHS on the top equation just to h... where did the [tex]2\pi[/tex] go..?
