Physics - Wave Optics Question with Solution | TestHub

Two wavelengths of sodium light $590\mathrm{nm}$ and $596\mathrm{nm}$ are used one after another to study diffraction due to single slit of aperture $2\times 10^{-6}\mathrm{m}$. The distance between the slit and the screen is $1.5\mathrm{m}$. The separation between the positions of first maximum of the diffraction pattern obtained in the two cases is
