A student is studying a Fraunhofer diffraction pattern. She measures the distance between the center of one dark fringe and the center of the next dark fringe some small distance from the central maximum, and finds them to be 4 mm apart. To get a high grade on her lab, she should predict that the distance between the dark fringes on either side of the central maximum will be
