A) \[({{\lambda }_{K}}-{{\lambda }_{C}})\]increases
B) \[({{\lambda }_{K}}-{{\lambda }_{C}})\,\]decreases
C) \[{{\lambda }_{K}}\] increases
D) \[{{\lambda }_{K}}\] decreases
Correct Answer: A
Solution :
Wavelength \[{{\lambda }_{k}}\] is independent of the accelerating voltage (V), while the minimum wavelength \[{{\lambda }_{c}}\] is inversely proportional to V. Therefore as V increases, \[{{\lambda }_{k}}\] remains unchanged whereas \[{{\lambda }_{c}}\] decreases or \[{{\lambda }_{k}}-{{\lambda }_{c}}\] will increase.
