Determine the wavelength of the second line of the Paschen series for hydrogen.

Explanation

To determine the wavelength of the second line of the Paschen series for hydrogen, we can follow these steps:

### Step 1: Understand the Paschen Series
The Paschen series corresponds to electronic transitions in a hydrogen atom where the electron falls to the third energy level (n=3) from higher energy levels (n=4, n=5, etc.). The second line of the Paschen series corresponds to the transition from n=5 to n=3.

### Step 2: Use the Rydberg Formula
The wavelength of the emitted light during these transitions can be calculated using the Rydberg formula:
