Physics - Wave Optics Question with Solution | TestHub

In Young's double slit experiment, the slits are $2\mathrm{mm}$ apart and are illuminated by photons of two wavelengths ${\lambda }_1=12000\mathring{A}$ and ${\lambda }_2=10000\mathring{A}$. At what minimum distance from the common central bright fringe on the screen $2\mathrm{m}$ from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?NEET 2013 (All India)
