Chemistry - Atomic Structure Question with Solution | TestHub

The shortest wavelength in hydrogen spectrum of Lyman series is given by formula
$\frac{1}{\mathrm{\lambda }}=\frac{{\mathrm{R}}_{\mathrm{H}}}{{\mathrm{n}}^2}=\frac{{\mathrm{R}}_{\mathrm{H}}}{1^2}=\frac{109678}{1}$
$\mathrm{\lambda }=9.117\times 10^{-6}\mathrm{c}\mathrm{m}$
$=911.7\times 10^{-10}\mathrm{m}=911.7\mathrm{\AA }$
