                              Lyman series             Balmer series

Limiting line:       n=  to  n=1        n=  to  n=2

                             EL>EB                     [Limiting case]

                             λL<λB

Rydberg constant represents the limiting value of the highest wavenumber of any photon that can be emitted from an atom  1λL=Z2R[λL=limiting   case]
