3 Determine the wavelength and frequency of the radiation having the longest wavelength in Lyman series of hydrogen atom R 109678 cm Ans Rydberg s equation R 11 In case of Lyman Ln n series n 1 n 2 or any other higher integral values 3 4 5 etc For the wavelength to be the longest the difference in energies between the two energy levels should be minimum Hence n 2
