Determine the minimum wavelength of a photon the can cause ionization of He ^(+) ion.

Explanation

To determine the minimum wavelength of a photon that can cause ionization of the He⁺ ion, we can follow these steps:

### Step 1: Determine the Ground State Energy of He⁺ Ion
The energy of an electron in a hydrogen-like atom is given by the formula:

\[ E_n = -\frac{13.6 \, Z^2}{n^2} \, \text{eV} \]
