A beam of light contains two wavelengths `6500Å` and `5200Å` They form interference fringes in Young's double slit experiment. What is the least distance (approx) from central maximum. Where the bright fringes due to both wavelength coincide? The distance between the slits is 2 mm and the distance of screen is 120 cm.

A beam of light consisting of two wavelengths, 650 nm and 520 nm is used to obtain interference fringes in Young's double-slit experiment. What is the least distance (in m) from a central maximum where the bright fringes due to both the wavelengths coincide ? The distance between the slits is 3 mm and the distance between the plane of the slits and the screen is 150 cm.

A beam of light consisting of two wavelengths 6500A^(0)" and "5200A^(0) is used to obtain interference fringes in a Young.s double slit experiment. What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide? Distance between the slits is 2mm, distance between the slits and the screen L= 120 cm .
