Consider only transitions involving the following energy levels for the h atom.
n =5
n = 4
n = 3
n = 2
n = 1
(a) how many emission lines are possible, considering only the five quantum levels?

(b) photons of the lowest frequency are emitted in a transition from the level with n = to a level with n =

(c) the emission line having the shortest wavelength corresponds to a transition from the level with n = the level with n =
(d) the emission line having the highest energy corresponds to a transition from the level with n = to the level with n =
