1. Designations from the early Balmer Series are in parentheses. 2. The Bohr assumptions recover the observed Balmer series. 3. The solution for the hydrogen atom describes standing waves of energy exactly given by the Balmer series. 4. Rydberg managed to find a formula to match the known Balmer series emission lines, and also predicted those not yet discovered. 5. Urey and grating spectrograph, a sensitive device that had been recently installed at Columbia and was capable of resolving the Balmer series. 6. At the limit of the Balmer series a change happens where at shorter wavelengths more bound-bound Balmer series transitions cause more opacity. 7. At the limit of the Balmer series a change happens where at shorter wavelengths more bound-bound Balmer series transitions cause more opacity. 8. Urey and his colleague George Murphy calculated the redshift of heavy hydrogen from the Balmer series and observed very faint lines on a spectrographic study. 9. I'm not entirely sure, but since 365.1nm is in the visible light spectrum that means it's in the Balmer series? 10. Emission lines of hydrogen ( mainly of the Lyman series and Balmer series ), helium, carbon, magnesium, iron and oxygen are the brightest lines.
