Lyman series transitions land at n = ___, lying in:
An = 1, ULTRAVIOLET
Bn = 2, visible
Cn = 3, infrared
Dn = 4, radio
Answer & Solution
Correct answer: A. n = 1, ULTRAVIOLET
Lyman: transitions to n = 1 (UV). Balmer: to n = 2 (visible, includes Hα = 656 nm). Paschen: to n = 3 (IR). Brackett: to n = 4 (far IR). Pfund: to n = 5.
