This is the only series of lines in the electromagnetic spectrum that lies in the visible region. When solving problems regarding the Rydberg formula, we have to use the values of principal quantum numbers for n 1 and n 2.Since n 1 < n 2, n 1 is the quantum number of the energy level to … Where R is Rydberg constant for the Hydrogen atom and equals to 1.1 10 7 m-1. Three years later, Rydberg generalized this so that it was possible to determine the wavelengths of any of the lines in the hydrogen emission spectrum. !☺☺ These states were visualized by the Bohr model of the hydrogen atom as being distinct orbits around the nucleus. The electromagnetic force between the electron and the nuclear proton leads to a set of quantum states for the electron, each with its own energy. Other spectral series … The so-called Lyman series of lines in the emission spectrum of hydrogen corresponds to transitions from various excited states to the n = 1 orbit. paschen and lyman series. �Jr Rydberg’s formula is given as: hc/λ = 21.76 x 10-19 [1/(n 1) 2 - 1/(n 2) 2] Where, h = Planck’s constant = 6.6 × 10 −34 Js. ‘See a 1922 paper by Frederick Brackett comparing Bohr's formula for the hydrogen spectral series with the Paschen series and with two members of a new series.’ Origin 1920s named after L.
