Vedclass · Answer

(A) The width of the central maximum in a single slit diffraction pattern is given by the formula $w = \frac{2 \lambda D}{a}$,where $\lambda$ is the wavelength of light,$D$ is the distance of the screen from the slit,and $a$ is the slit width.From this relation,it is clear that the width of the central maximum $w$ is inversely proportional to the slit width $a$ $(w \propto \frac{1}{a})$.Therefore,if the slit width $a$ is decreased,the width of the central maximum $w$ increases.This relationship holds true for both Fresnel and Fraunhofer diffraction patterns as the fundamental geometric dependence on the aperture size remains consistent.
