You shine a laser on a pair of closely spaced slits. By turning a knob, you can change the spacing of the slits. (The wavelength of the laser light remains constant.) Initially, the slits are 0.300 mm apart. You change the spacing of the slits so that the m=2 bright fringe moves to the position initially occupied by the m=3 bright fringe. What is the new spacing of the slits?
