use the RYDBERG formula to suggest a possible transition that would result in the observed wavelength
Hydrogen - yellow wavelength about 600nm
The Attempt at a Solution
I used c= lambda x frequency(V) and found (V) to equal 5e14/second
I then used energy(E) = constant(h) x V and found E to equal 3.32e-19j
Last i used En = (-2.178e-18j)/n^2 to find the transition, I did 3.32e-19j = (-2.178e-18j)/n^2 and found n^2 to equal -6.57014 and I'm stuck there because it's a negative number...
