09 A beam of light consisting of two wavelengths 800 nm and 600 nm The beam is used to obtain interference fringes in Young s double slit experiment screen kept at a distance 1 4 m away from slits The slits are separated by a distance of 0 28 mm The least distance from central maximum where bright fringes of two wavelengths coincide is O A 3rd bright of 800 nm will coincide with 4th bright of 600 nm O B 4th bright of 800 nm will coincide with 3rd bright of 600 nm C 3rd bright of 800 nm will coincide with 2nd bright of 600 nm O D 2nd bright of 800 nm will coincide with 3rd bright of 600 nm
