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 accelerating potential difference is changed only the minimum wavelength changes. |
It has no effect on wavelengths of characteristic x-rays (whether they are produced or not) |
\[\therefore \][c] is the correct choice. |
