What is the shortest wavelength present in the Paschen series of spectral lines?

Explanation

To find the shortest wavelength present in the Paschen series of spectral lines, we will use the Rydberg formula, which is given by:

\[ \frac{1}{\lambda} = R \left( \frac{1}{n_1^2} - \frac{1}{n_2^2} \right) \]

where:
- \( \lambda \) is the wavelength,
