\mathrm{\frac{1}{\lambda_0}=R\left(\frac{1}{22}-\frac{1}{32}\right)=R\left(\frac{1}{4}-\frac{1}{9}\right)=\frac{5 R}{36}-1 }

\mathrm{\frac{1}{\lambda^{\prime}}=R\left(\frac{1}{22}-\frac{1}{42}\right)=R\left(\frac{1}{4}-\frac{1}{16}\right)=\frac{3 }{4}\frac{R}{16}-(2) }

\mathrm{ \Rightarrow \lambda^{\prime}=\frac{20}{27} \, \lambda_0 }
