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 depends on the electrical 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

B

Explanation

`lamda_0=(hc)/(eV)`
It is independent of atomic number of target.
