### 1A.11 Question on Balmer and Lyman series

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?

Could someone help me understand what Balmer and Lyman series are and how they relate to the properties of light?

The lines in these series are grouped together because their lower energy level have the same principle quantum number. For the Layman series, n=1 for the lower energy level. For the Balmer series, n=2 for the lower energy level.

Balmer and Lyman series are a series of spectral line emissions in hydrogen atoms.
Each absorption line (each series) is the quantum number of the lower energy level (n=1 through 6).
These spectral lines are caused by electrons crossing between two levels of energy, producing light.
