Calculate the wavelength (λ in nm) of the photon emitted when an electron transitions between n = 3 and n = 1 energy levels. I keep getting .00975 but the answer is apparently 102.6nm could someone please explain this to me?

ah wait its not what you need, sorry
OpenStudy (somy):
can u show your working?
OpenStudy (jfraser):
0.00975 is the INVERSE of the wavelength. If you divide 1/0.00975 you'll get 102nm
