Find the maximum frequency, the X-ray emitted by an X-ray tube operating at `30 kV`

Explanation

To find the maximum frequency of the X-ray emitted by an X-ray tube operating at 30 kV, we can follow these steps:

### Step 1: Understand the relationship between energy and frequency
The energy of a photon is given by the equation:
\[ E = h \nu \]
where:
- \( E \) is the energy of the photon,
- \( h \) is Planck's constant (\( 6.626 \times 10^{-34} \, \text{Js} \)),
