Which one of the following statement is `WRONG` in the context of X- rays generated from X- rays tube ?

Options

A. wavelength of characteristic X-rays decreases when the atomic number of the target increases.
B. Cut-off wavelength of the continuous X-rays depends on the atomic number of the target.
C. Intensity of the characteristic X-rays depend on the electric power given to the X-ray tube.
D. Cut-off wavelength of the continuous X-rays depends on the energy of the electrons in the X-ray tube.

Answer

C

Explanation

Cut-off wavelength depends on the applied voltage and not on the atomic number of the target. Characteristic wavelength depends on the atomic number of the target
