Which statement is false about the width of the central maximum of a circular-aperture diffraction pattern?
[a]if the size of the aperture (d) is increased, then the circular spot increases in size.[b]if the distance to the screen (l) increases, then the circular spot increases in size.[c]the width of the central bright spot from a circular aperture is 1.22 times wider than the central bright band produced from a single-slit aperture if the circular aperture width has the same width as the single slit.[d]if the size of the aperture (d) is increased, then the circular spot decreases in size.
