Final answer:
The Lyman, Balmer, and Paschen series are spectral lines associated with the hydrogen atom.
Step-by-step explanation:
The Lyman, Balmer, and Paschen series are spectral lines associated with the hydrogen atom.
The Lyman series refers to spectral lines in the ultraviolet region of the spectrum that result from electron transitions ending in the ground state (n=1).
The Balmer series includes spectral lines in the visible spectrum, which arise from transitions to the second energy level (n=2).
The Paschen series, on the other hand, represents infrared spectral lines resulting from transitions to higher energy levels (n > 2).
