Young s double slit experiment a point source is placed on a solid slab of refractive index 6 5 at a distance of 2 mm from two slits spaced 3 mm apart as shown and at equal distance from both the slits The screen is at a distance of I m from the slits Wavelength of light used is 500 nm K S 2 mm 26 l 6 5 3 mm The central maxima is at 6 The central maxima is at 1 Im m below O m below O 600 The order of the fringe formed at O is 750 B If a film of refractive index 1 8 is to be placed in front of S so that central maxima is formed where 200th maxima was formed Then the thickness of film is 1
