The series of emission lines of the hydrogen atom for which n f = 3 is called the Paschen series. (a) Determine the region of the electromagnetic spectrum in which the lines of the Paschen series are observed. (b) Calculate the wavelengths of the first three lines in the Paschen series-those for which n, = 4, 5, and 6.
