To compute the wave number that is the inverse of wavelength we use the formula Humphreys series, Categories: Emission spectroscopy | Hydrogen physics. Paschen series are the series of lines in the spectrum of the hydrogen atom which corresponds to transitions between the state with principal quantum number n = 3 and successive higher states. For the shortest wavelength in Paschen series, n2 = ∞ and n1 = 3 Using Rydberg s formula, 1λ = R 1n12 - 1n22 where, the value of R is 1.097 × 107 m-1.Therefore, 1λmin = R132-1∞2 = R9⇒ λmin = 9R = 91.097 × 107mi.e., λmin = 9 × 10-7 × 10101.097Å = 8204.2 Å, is the value of the shortest wavelength. 1 875 nm c. 1 923 nm d. 2 251 nm What is the value of the lowest energy transition for the Paschen series for a single electron?
