Consider only transitions involving the n = 1 through n = 5 energy levels for the H atom (see Figures 6.7 and 6.10). 

(a) How many emission lines are possible, considering only the five quantum levels? 

(b) Photons of the highest frequency are emitted in a transition from the level with n= __________ to a level with n =__________ . 

(c) The emission line having the longest wavelength corresponds to a transition from the level with n =__________ to the level with n = __________.

The difference between successive energy levels becomes smaller as n becomes larger.
