Q. STATEMENT-1 : If the accelerating potential in an $X$ - ray tube is increased, the wavelengths of the characteristic $X$-rays do not change
because
STATEMENT-2 : When an electron beam strikes the target in an $X$-ray tube, part of the kinetic energy is converted into $X$-ray energy.

Solution:

We have
$\lambda_{ cut -\text { in }}=\frac{h c}{e V}$
Accelerating potential in an $X$-ray tube can affect the cut-in voltage of the continuous spectrum, but not the characteristic spectrum.
