Calculate the wavelength of radiation emitted when `He^(+)` makes a transtion from the state `n = 3` to the state `n = 2`

Explanation

To calculate the wavelength of radiation emitted when \( \text{He}^+ \) makes a transition from the state \( n = 3 \) to the state \( n = 2 \), we can follow these steps:

### Step 1: Identify the parameters
We know that:
- The atomic number \( Z \) for helium \( \text{He}^+ \) is 2.
- The initial state \( n = 3 \) (old orbit).
- The final state \( n = 2 \) (new orbit).
