Question

The wavelength of first line of Lyman series of H-atom is 1216 Å. What will be the wavelength of first line of Lyman series in 10 time ionized sodium atom (Z = 11)?

Accepted Answer

$\lambda \propto \frac{1}{z^{2}} \Rightarrow \frac{\lambda_{Na^{10 +}}}{\lambda_{H}} = \frac{1^{2}}{10^{2}} \Rightarrow \lambda_{Na^{10 +}} = 12.16\overset{o}{A}$
