A beam of light of $\displaystyle \lambda=600 \mathrm{~nm}$ from a distant source falls on a single slit $\displaystyle 1$ mm wide and the resulting diffraction pattern is observed on a screen $\displaystyle 2$ m away. The distance between first dark fringes on either side of the central bright fringe is :
