Vedclass · Answer

(D) In a single-slit diffraction experiment, the angular width of the central maxima is given by the formula $	heta = \frac{2\lambda}{a}$, where $\lambda$ is the wavelength of the light used and $a$ is the width of the slit.From this formula, it is clear that the angular width depends on the wavelength $\lambda$ and the slit width $a$.It also depends on the ratio $\frac{\lambda}{a}$.However, the angular width does not depend on the distance $D$ between the slit and the screen.

In a diffraction experiment from a single slit, the angular width of the central maxima does $NOT$ depend upon
