A group of students preform the single slit diffraction laboratory. The distance from the single slit screen is $(99\mathrm{.}11)$ cm$.$ They measure the position of the first order minima in the diffraction pattern to be: m $=1,$ y $+1=0\mathrm{.}0430$ m and m $=-1,$ y$-1=0\mathrm{.}0353$ m$.$ Determine the aperture of the slit for this experiment $($with uncertainty$).$ Compare your result with the accepted value of $0\mathrm{.}16$ mm
