### 1.11

What is common to the lines within a series that makes grouping them together logical?

Waves in a series all have similar wavelengths and all transition their electron to the same energy level. i.e the Lyman series are all ultraviolet waves that drop to n1, paschen's are all infrared and fall to n3

What groups these spectral lines together is their lower energy level. An energy level is a permitted value of the energy in a quantized system such as an atom or a molecule.

For example, the Balmer series is a set of lines in the visible light region of the electromagnetic radiation spectrum with their lowest energy level being n₁ = 2. The lyman series is a set of lines in the ultraviolet region of the spectrum with their lowest energy level being n₁ = 1.

Note that the difference in the energies of two levels is what gets carried away by the electromagnetic radiation emitted by the atom or molecule.
