Q2. Light of a particular wavelength shines on a single slit of width 1.150e-4 m, creating a diffraction pattern with the first dark fringe at an angle of 0.224° from the centerline. If the similar light shines in its place on two even narrower slits, the interference pattern has its first dark fringe (the one adjacent to the central maximum) at the same angle. What is the distance between the centers of the two slits? Describe answer in m.
