Question

Consider the spectral line resulting from the transition $\mathrm{n}=2$ to $\mathrm{n}=1$ in the atoms and ions given below. The shortest wavelength is produced by\

Professor PC Thomas Classes · Answer

$\frac{1}{\lambda}=\mathrm{R}\left(\frac{1}{\mathrm{n}_{1}^{2}}-\frac{1}{\mathrm{n}_{2}^{2}}ight)$ for hydrogen\ $\frac{1}{\lambda}=\mathrm{Z}^{2} \mathrm{R}\left(\frac{1}{\mathrm{n}_{1}^{2}}-\frac{1}{\mathrm{n}_{2}^{2}}ight)$ for hydrogen like atom.\ When Z is maximum $\lambda$ is minimum. Z is\ Maximum for Lithium.\
