Five lines in the H atom spectrum have these wavelengths (in Å): (a) 1212.7; (b) 4340.5; (c) 4861.3; (d) 6562.8; (e) 10,938. Three lines result from transitions to n_final=2 (visible series). The other two result from transitions in different series, one with n_final=1 and the other with n_final=3 . Identify n_initial for each line.
