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

Vedclass · Answer

(B) The cut-off wavelength $(\lambda_{min})$ of continuous $X-$rays is given by the formula $\lambda_{min} = \frac{hc}{eV}$, where $h$ is Planck's constant, $c$ is the speed of light, $e$ is the charge of an electron, and $V$ is the accelerating potential difference.This formula shows that $\lambda_{min}$ depends only on the accelerating voltage $V$ (which determines the energy of the electrons) and fundamental constants.It does not depend on 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 $WRONG$.
