A light source, width emits two wavelengths \(\lambda\)1 = 400 nm and \(\lambda\)2 = 600 nm, is used in a Young's double-slit experiment. If recorded fringe widths for \(\lambda\)1 and \(\lambda\)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 m1 and m2, respectively, then
