A parallel beam of electrons, travelling in $x$ -direction, falls on a slit of width $d$ (see the figure). If after passing the slit, an electron acquires momentum $P_{y}$ in the $y$ -direction, then for a majority of electrons passing through the slit, ( $h$ is Planck's constant)

Answer:

A

Solution:

$\sin θ = \frac{λ}{d}$

$\sin θ \leq 1$

$λ = \frac{h}{p}$
