Problem
Three prominent emission lines of atomic hydrogen have wavelengths 1875nm, 656.3nm and 121.6nm respectively.
(i) For each wavelength, identify the spectral series to which the line belongs.
(ii) Determine, in each case, the initial and final principal quantum numbers involved in the transition.
(iii) Arrange the three lines in the increasing order of photon energy released, showing your reasoning clearly.
