Physics - Wave Optics Question with Solution | TestHub

For a parallel beam of monochromatic light of wavelength$\mathrm{\lambda }$, diffraction is produced by a single slit whose width$\text{a}$is of the order of the wavelength of the light. If$\text{D}$is the distance of the screen from the slit, the width of the central maxima will be:NEET 2015 (Phase 1)
