In the atomic spectrum of hydrogen, the wavelengths of the spectral lines corresponding to electronic transitions (i) $n=4$ to $n=2$ and (ii) $n=3$ to $n=1$ are $\lambda_1$ and $\lambda_2 Å$ respectively. The value of $\left(\lambda_1-\lambda_2\right)$ (in cm) is $\left(\mathrm{R}_{\mathrm{H}}=\right.$ Rydberg constant $)$

• A

  $\frac{1}{\mathrm{R}_{\mathrm{H}}}\left[\frac{24}{101}\right]$
• B

  $\mathrm{R}_{\mathrm{H}}\left[\frac{24}{101}\right]$
• Correct answer
  C

  $\frac{1}{\mathrm{R}_{\mathrm{H}}}\left[\frac{101}{24}\right]$
• D

  $\mathrm{R}_{\mathrm{H}}\left[\frac{101}{24}\right]$

Hence, the correct answer is option: 'C'.
