Find the cutoff wavelength for the continuous X-rays coming form an X-ray tube operating at 30 kV.

Explanation

To find the cutoff wavelength for the continuous X-rays coming from an X-ray tube operating at 30 kV, we can use the formula:

\[ \lambda = \frac{hc}{eV} \]

where:
- \(\lambda\) is the cutoff wavelength,
