Question

STATEMENT-1: If the accelerating potential in an X-ray tube is increased, the wavelengths of the characteristic X-rays do not change.

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. [2007]

Note: Shortest wavelength means highest frequency, so highest energy.

Shortest or cut-off wavelength of X-rays emitted from an X-ray tube depends on the voltage applied to the tube.

Also, according to Moseley's law, $\sqrt{ν} = a (Z - b) .$ Thus, the frequency also depends on the atomic number.
