We have λ cut - text in =(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.

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.

Statement- 1 is True, Statement- 2 is True; Statement- 2 is a correct explanation for Statement-1

Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1

Statement-1 is True, Statement-2 is False.

Statement-1 is False, Statement-2 is True.

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