A light source, which emits two wavelength `lamda_(1)=400nm` and `lamda_(2)=600nm`, is used in a Young's double slit experiment. If recorded fringe width for `lamda_(1)` and `lamda_(2)` are `beta_(1)` and `beta_(2)` and the number of fringes for them within a distance y on one side of the central maximum are `m_(1)` and `m_(2)` respectively, then
