calculate the wavelength in nm of the spectral line produced when an electron in an hydrogen atom undergoes the transition from n=3 to n=2.
I get 6.56x10^-7 meters and 6,561.68 nm but that is not the right answer...help please!
Using 1.0973732E7 for Rydberg constant, I get 6.56112E-7 and that is 656.112 nm. I suspect you didn't convert to nm correctly. I don't know how many s.lf. you are to quote.
