Question

A single-slit diffraction pattern is formed on a distant screen. If the width of the single slit through which light passes is reduced, what happens to the width of the central bright fringe? Assume the angles involved remain small.
The effect cannot be determined unless the distance between the slit and the screen is known.
The central bright fringe becomes wider.
The central bright fringe becomes narrower.
The central bright fringe remains the same size.
