Homework Statement


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.


Homework Equations


En=E1/n^2


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 don't know how to find the energy level it started from

Welcome to PF,

HINT: What energy does the de Broglie wavelength correspond to? Where did this energy come from?

The pfund series starts from n=5, and includes transitions to higher energy levels, as stated in the question.
