Both $(I)$ and $(II)$

Vedclass · Answer

(D) In a single slit diffraction pattern,the width of the central maxima is given by $w = 2\lambda D/a$,while the width of secondary maxima is $\lambda D/a$.Thus,the central maxima is twice as wide as the secondary maxima (Statement $I$ is correct).The intensity of the secondary maxima decreases rapidly as we move away from the central maxima (Statement $II$ is correct).The width of the central maxima is inversely proportional to the slit width $a$ (Statement $III$ is incorrect).The intensity of the central maxima is much higher than that of the secondary maxima (Statement $IV$ is incorrect).Therefore,statements $I$ and $II$ are correct.
