A) remain unchanged
B) become four times
C) become two times
D) become half
Correct Answer: D
Solution :
According to de-Broglie theory, the wavelength \[\lambda =\frac{\text{Plank }\!\!\!\!\text{ s}\,\text{constant}}{\text{momentum}}\]\[\Rightarrow \]\[\lambda \propto \frac{1}{p}\] Hence, if momentum of particle is doubled then it is clear that wavelength will become half.
