## hydrogen spectrumThe Lyman series involve jumps to or from the ground state (n=1); the Balmer series (in which all the lines are in the visible region) corresponds to n=2, the Paschen series to n=3, the Brackett series to n=4, and the Pfund series to n=5. To illustrate with specific values, consider the Balmer series, in which the four principal lines, designated as H-alpha, H-beta, H-gamma, and H-delta, involve energy jumps of 3.02 × 10 ^{-19}, 4.07 × 10^{-19},
4.57 × 10^{-19}, and 4.84 × ^{-19} joules (J),
respectively, and corresponding photons of wavelengths are 656.3, 486.1,
434.0, and 410.2 nanometers (nm). ## Related categories• SPECTRA AND SPECTROSCOPY• ATOMIC AND NUCLEAR PHYSICS | ||||||
