Write a relation for the wavelength in Paschan series lines of hydrogen. Spectrum.

Explanation

To derive the relation for the wavelength of the Paschen series lines in the hydrogen spectrum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Paschen Series**:
The Paschen series corresponds to electronic transitions in hydrogen where the electron falls from a higher energy level (n2) to the n=3 energy level.

2. **Using the Rydberg Formula**:
...
