Find the wavelength present in the radiation emitted when hydrogen atoms emitted to `n = 3` states return to their ground state.

Explanation

To find the wavelength of the radiation emitted when hydrogen atoms transition from the \( n = 3 \) state to their ground state (\( n = 1 \)), we can follow these steps:

### Step 1: Determine Energy Levels
The energy levels of the hydrogen atom are given by the formula:
\[ E_n = -\frac{13.6 \, \text{eV}}{n^2} \]
where \( n \) is the principal quantum number.
