Question

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 (Nearest inteter)
