In a Young's double slit experiment ,a thin sheet of refractive index 1.6 is used to cover one slit while a thin the sheet of refractive index 1.3 is used to cover the second slit. The thickness of both the sheets are same and the wavelength of light used is 600 nm. If the central point on the screen in now occupied by what had been the 10th bring fringe (m=10 ) , then the thickness of covering sheets is
