a) If you examine the spectral lines in the Balmer series, they seem to bunch up closely at one end. Examine the Rydberg formula and see if it suggests that such bunching occurs. b) What value should be taken for ni in the Rydberg equation to compute the wavelength of the spectral line of a series limit? c) Compute the wavelength of the series limit for the Lyman, Balmer and Paschen series of the hydrogen emission spectrum. d) How much energy (in J and in eV) does a photon of light with a wavelength corresponding to the series limit of the Lyman series have? (b. c. 90.0 nm, 364 nm, 818 nm d. 2.19 x 10-18 J, 13.7 eV)
