A double-slit diffraction pattern is formed on a distant screen. If the separation between the slits decreases, what happens to the distance between interference fringes? Assume the angles involved remain small. The distance between interference fringes remains the same. The effect cannot be determined unless the distance between the slits and the screen is known. The distance between interference fringes also decreases. The distance between interference fringes increases.
