A) the frequency of characteristic x - rays of a material will get changed
B) number of electrons emitted will change
C) the difference between \[{{\lambda }_{0}}\] (minimum wavelength) and \[{{\lambda }_{k\alpha }}\] (wavelength of \[{{k}_{\alpha }}x-ray\]) will get changed
D) difference between \[{{\lambda }_{k\alpha }}\] and \[{{\lambda }_{k\beta }}\] will get changed.
Correct Answer: C
Solution :
As the acceleration potential difference is changed only the minimum wavelength changes. It has no effect on wavelengths of characteristics x-rays (whether they are produced or not) \[\therefore \] [c] is the correct choice.
