Q. The de Broglie wavelength of the matter wave associated with an object dropped from a height $x$, when it reaches the ground is proportional to
KEAM
KEAM 2020
A
$x^2$
B
$\frac{1}{\sqrt{x}}$
C
$\sqrt{x}$
D
$x^{3/2}$
E
$x$
Solution:
$\lambda=\frac{h}{m V}=\frac{h}{m \sqrt{2 g n}}$
$\Rightarrow \lambda \alpha \frac{1}{\sqrt{x}}$
