Structure of Atom · Hydrogen spectrum spectral series

The hydrogen spectrum consists of several spectral lines in Lyman series (L1L_1, L2L_2, L3L_3 …; L1L_1 has lowest energy among Lyman series). Similarly it consists of several spectral lines in Balmer series (B1B_1, B2B_2, B3B_3 …; B1B_1 has lowest energy among Balmer lines). The energy of L1L_1 is xx times the energy of B1B_1. The value of xx is × 10−1\times\,10^{-1} (Nearest integer)
