### 1A.11

I understand how the series are related to energy levels, but I don't understand the answer for this question.

"In the spectrum of atomic hydrogen, several lines are generally classified together as belonging to a series (for example, Balmer series or Lyman series, as shown in Fig. 1A.10). What is common to the lines within a series that makes grouping them together logical?"

For this question, I said that the lines within a series share the same quantum number for the lower energy level (in which the electron returns to after being excited). This number is associated with the Lyman series for n=1 or Balmer for n=2.

What does it mean that the principle quantum number for the lowest energy level is the same for each series?
