A sample of hydrogen atoms is excited in such a way that allelectrons in atoms are positioned in the n=4 level. Then the sampleis left to itself, and electrons eventually transit to the groundlevel. How many lines will be observed in the emission spectrum?What are their wavelengths? Hint: the transition to he ground levelmay occur either directly (4-->1) or in more than one step (e.g.4-->3-->1).
