Physics Question from JEE Main 2023 · 31 January, Shift 2

Two light waves of wavelengths $800 \, \text{nm}$ and $600 \, \text{nm}$ are used in Young's double slit experiment to obtain interference fringes on a screen placed $7 \, \text{m}$ away from the plane of slits. If the two slits are separated by $0.35 \, \text{mm}$, then the shortest distance from the central bright maximum to the point where the bright fringes of the two wavelengths coincide will be ...... $\text{mm}$.
