A beam of light consisting of two wavelengths 7000 `dot A` and 5500 `dot A` is used to obtain interference pattern in young's double slit experiment.The distance between the slits is 2.5 mm and the distance between the plane of slits and the screen is 150cm.The least distance from the central fringe,where the bright fringes due to both the wavelengths coincide,is `n xx 10^-5` m. The value of n is ______

A beam of light consisting of two wavelength 6500Å&5200Å is used to obtain interferance fringes in a young's double slit experiment .The distance between the slits is 2.0mm and the distance between the plane of the slits and thescreen is 120cm ,.what is the least distance from the central maximum where the bright fringes due to both the wave length coincides?
