Briefly explain why the transitions associated with the Lyman series correspond to wavelengths in the ultraviolet region of the electromagnetic spectrum.

  • chem -

    Briefly, the series starting with n=2 to n=1, and going to n= 10 to n=1, are much more energetic than those of the other series because of the energy differences of the levels involved. Therefore, the Lyman series is in the ultraviolet and not in the visible or infrared.
