Parts and their functions

• Lyman series (n₁ = 1) (लाइमन श्रेणी (n₁ = 1)) — Electron falls to n = 1 from n = 2, 3, … — ultraviolet lines.
• Balmer series (n₁ = 2) (बामर श्रेणी (n₁ = 2)) — Falls to n = 2 — the only series in the visible region (e.g. 4 → 2 gives 486 nm).
• Paschen series (n₁ = 3) (पाशन श्रेणी (n₁ = 3)) — Infrared lines.
• Brackett series (n₁ = 4) (ब्रैकेट श्रेणी (n₁ = 4)) — Infrared lines.
• Pfund series (n₁ = 5) (फुंड श्रेणी (n₁ = 5)) — Far infrared lines.
