A) directly proportional to its energy
B) directly proportional to momentum
C) inversely proportional to its energy
D) inversely proportional to momentum
Correct Answer: D
Solution :
The de-Broglie equation is given as \[\lambda =\frac{h}{m\upsilon }=\frac{h}{P}\] (P = momentum) Hence, \[\lambda \propto \frac{1}{P}\] i.e., Wavelength \[\propto \frac{1}{\text{momentum}}\]
