Q. The de-Broglie wavelength $L$ associated with an elementary particle of linear momentum $p$ is best represented by the graph
A) [image:11_image28.emf]
B) [image:11_image29.emf]
C) [image:11_image30.emf]
D) [image:11_image31.emf]
Explanation
(d) $\lambda = \frac{h}{p}$ or $L = \frac{h}{p}ie,\ L \propto \frac{1}{p}$. The curve (d) is correct.
