hydrogen spectrum

In the spectrum of atomic hydrogen, several lines are generally classified together as belonging to a series (for example, Balmer series, Lyman series, Paschen series), What is common to the lines within a series that makes grouping them together logical?


The answers say that each series has a different lower energy level, can anyone pls explain




The Lyman series is made of lines in the spectrum corresponding to the return of the electron from a higher level ($n = 2, 3, 4,$ etc.) to the first and deepest level ($n = 1$) .


The Balmer series is made of lines in the spectrum corresponding to the return of the electron from a higher level ($n = 3, 4, 5$, etc.) to the second level ($n = 2$)


The Paschen series is made of lines in the spectrum corresponding to the return of the electron from a higher level ($n = 4, 5,$ etc.) to the third level ($n = 3$)
