in the line spectrum of atomic hydrogen there is also a group of lines known as the pfund series. these lines are produced when the electrons, excited to high energy levels, make transitions to the n=5 level.

Determine (a) the longest wavelength and the (b) shortest wavelength in this series. (c) what region in the electromagnetic spectrum in which these lines are found.

2. Relevant equations

En=E1/n^2

3. The attempt at a solution

i think i have to find the energy levels it could have started from

and then find the biggest jump and smallest made. but i dont know how to find the energy level it started from
