Suppose we have 15 parallel long narrow slits in an opaque screen. Furthermore, suppose each slit is separated from the next by a center-to-center distance that is equal to 4 slit widths. Given that a Fraunhofer diffraction pattern appears on a screen, determine the ratio of the irradiance of the second-order principal maximum to that of the zeroth-order maximum.
