Vedclass · Answer

(D) In a single slit diffraction pattern,the intensity of the central maximum is proportional to the square of the slit width $(a^2)$.Let the initial slit width be $a$ and the initial intensity be $I_0 \propto a^2$.When the slit width is doubled,the new width becomes $a' = 2a$.The new intensity $I'$ will be proportional to the square of the new width: $I' \propto (a')^2 = (2a)^2 = 4a^2$.Since $I_0 \propto a^2$,we have $I' = 4I_0$.Therefore,when the slit width is doubled,the intensity of the principal maximum becomes four times the original intensity.
