Chemistry Question from JEE Main 2026 · 24 January, Shift 1

The hydrogen spectrum consists of several spectral lines in Lyman series ($L_1$, $L_2$, $L_3$ \dots; $L_1$ has lowest energy among Lyman series). Similarly, it consists of several spectral lines in Balmer series ($B_1$, $B_2$, $B_3$ \dots; $B_1$ has lowest energy among Balmer lines). The energy of $L_1$ is $x$ times the energy of $B_1$. The value of $x$ is _____ $\times 10^{-1}$. (Nearest integer)
