Lyman series is obtained when an electron jumps to the first orbit $\left(n_1=1\right)$ from any outer orbit $\left(n_2=2,3,4\dots \right)$ $$\frac{1}{\lambda }=RZ\left[\frac{1}{n_1^2}-\frac{1}{n_2^2}\right]$$ For $H,Z=1$ and $R$ is the Rydberg's constant $R=1.097\times 10^7{\mathrm{m}}^{-1}$. In this series, the shortest wavelength or the limit of this series (For $n_1=1$ and $n_2=\infty$ ) is nearly $=911\mathring{A}$
