Structure of Atom Part 2

The hydrogen spectrum consists of several spectral lines in Lyman series (L1,L2,L3...;L1. has lowest energy among Lyman series). Similarly it consists of several spectral lines in Balmer series ( B1,B2,B3...;B1 has lowest energy among Balmer lines). The energy of L1 is x times the energy of B1. The value of x is ____ ×10−1
