Find the minimum wavelngth of `X` - ray emitted by `X` - ray tube , which is operating at `15 kV` accelerating voltage.

Explanation

To find the minimum wavelength of X-rays emitted by an X-ray tube operating at an accelerating voltage of 15 kV, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Energy of the Accelerated Electrons**:
The energy (E) of the electrons accelerated through a potential difference (V) is given by the formula:
\[
E = eV
