Question 131 of 239

The first three spectral lines of $H$-atom in the Balmer series are given ${\lambda }_{1},{\lambda }_{2},{\lambda }_{3}$ considering the Bohr atomic model, the wave lengths of first and third spectral lines $\left(\dfrac{{\lambda }_{1}}{{\lambda }_{3}}\right)$ are related by a factor of approximately $x$ $\times {10}^{-1}$. The value of $x$, to the nearest integer, is ________.
