JEE MainPhysicsWave OpticsNumerical+4 / −1
Two light waves of wavelengths 800 and 600 nm600 \mathrm{~nm}600 nm are used in Young's double slit experiment to obtain interference fringes on a screen placed 7 m7 \mathrm{~m}7 m away from plane of slits. If the two slits are separated by 0.35 mm0.35 \mathrm{~mm}0.35 mm, then shortest distance from the central bright maximum to the point where the bright fringes of the two wavelength coincide will be ‾mm\underline{\hspace{2cm}}\mathrm{mm}​mm.
