In figure, parallel beam of light is incident on the plane of the slits of a Young's double-slit experiment. Light incident on the slit S_(1) passes through a medium of variable refractive index mu = 1 + ax (where 'x' is the distance from the plane of slits as shown), up to distance 'I' before falling on S_(1) . Rest of the space is filled with air. If at 'O' a minima is formed. then the minimum value of the positive constant a (in terms of l and wavelength lambda in air) is
