% error in the estimated wavelength. A 1% uncertainty in the spacing between the diffraction minima will yield a You use the interference pattern from a single slit to measure the wavelength of your laser. A 1% systematic error in the distance from the slit to the screen will lead to a % uncertainty in the estimated wavelength.
