Monochromatic light illuminates a pair of thin parallel slits at normal incidence, producing an interference pattern on a distant screen. The width of each slit is 1/7 the center-to-center distance between the slits.
(a) Which interference rnaxima are missing in the pattern on the screen?
(b) Does the answer to part (a) depend on the wavelength of the light used? Does the location of the missing rnaxima depend on the wavelength?
