Vedclass · Answer

(A) When electrons pass through a narrow slit of width '$d$' comparable to their de Broglie wavelength, they exhibit wave-like behavior and undergo diffraction. According to the single-slit diffraction pattern, the intensity (or number of electrons '$N$') is maximum at the center $(y = 0)$. The first minima occur at positions given by the condition $d \sin 	heta = \lambda$, where $	heta \approx y/D$. Thus, $y = \pm \lambda D / d$. Since the wavelength $\lambda$ is comparable to '$d$', the width of the central maximum is significant, and the diffraction pattern spreads out. Graph $A$ represents the standard intensity distribution for single-slit diffraction, where the central maximum is at $y = 0$ and the intensity drops to zero at $y = \pm \lambda D / d$.
