Imagine two aperture screens arranged to produce two Fraunhofer diffraction patterns. One contains 8 very narrow closely spaced parallel slits, the other 16 such slits. All else being equal, compare the two irradiance distributions. That is, how many subsidiary maxima between consecutive principal maxima will each pattern contain? If the irradiance of the zeroth-order peak of the 16-slit pattern is set equal to 1.0, how big will the corresponding peak be for the 8-slit pattern? Which arrangement produces wider principal maxima? Draw a rough sketch of each.
