Physics - Wave Optics Question with Solution | TestHub

In a Young's double slit experiment, the intensity at a point is ${\left(\frac{1}{4}\right)}^{\text{th }}$ of the maximum intensity, the minimum distance of the point from the central maximum is ________ $\mu \mathrm{m}$. (Given : $\lambda =600\mathrm{nm},\mathrm{d}=1.0\mathrm{mm},\mathrm{D}=1.0\mathrm{m}$ )
