A) Temperature of target is increased
B) Intensity of electron beam is increased
C) K.E. of electrons striking the target is increased
D) K.E. of electrons striking the target is decreased
Correct Answer: C
Solution :
\[{{\lambda }_{\min }}=\frac{hc}{eV\text{(energy)}};\] when \[KE\] (or \[eV)\] increases, \[\lambda \] decreases.
