Cut-off wavelength of the continuous $X$-rays depends on the atomic number of the target.

(B) The cut-off wavelength $(\lambda_{\text{min}})$ of continuous $X$-rays is given by the formula $\lambda_{\text{min}} = \frac{hc}{eV}$, where $V$ is the accelerating potential difference.This formula shows that the cut-off wavelength depends only on the accelerating voltage $(V)$ and is independent of the atomic number $(Z)$ of the target material.Therefore, the statement that the cut-off wavelength depends on the atomic number of the target is $WRONG$.
