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 decrease when the atomic number of the target increases
B. Cut-off wavelength of the continous X-rays depend on the atomic number of the target
C. Intensity of the characteristic X-rays depend on the electrical power given to the X-rays tube
D. Cut-off wavelength of the continous X-rays depend on the energy of the electronsin the X-rays tube.

Answer

B

Explanation

`lambda_(c)=(hc)/(eV)` independent of atomic no. of target
