The fringes have equal width and equal intensity.

Vedclass · Answer

(D) In a single slit diffraction pattern,the central maximum is the brightest and widest. As we move away from the center,the intensity of the secondary maxima decreases rapidly. The width of the central maximum is $2\lambda D/a$,while the width of the secondary maxima is $\lambda D/a$. Therefore,the fringes have unequal width and unequal intensity. Option $D$ states that the fringes have equal width and equal intensity,which is incorrect.
