None of the above

Vedclass · Answer

(D) In a single slit diffraction pattern,the central maximum is the brightest and widest. The width of the central maximum is given by $\beta_0 = \frac{2\lambda D}{a}$,where $\lambda$ is the wavelength,$D$ is the distance to the screen,and $a$ is the slit width. The width of the secondary maxima is given by $\beta = \frac{\lambda D}{a}$. Therefore,the central fringe has a width double that of the other fringes. Since none of the options $A$,$B$,or $C$ correctly describe this property,the correct answer is $D$.
