A diffraction experiment involving two thin parallel slits yields the pattern of closely spaced bright and dark fringes shown in the following figure. Only the central portion of the pattern is shown in the figure. The bright spots are equally spaced at d = 1.57 mm center to center (except for the missing spots) on a screen 2.15 m from the slits.

You send coherent 550 nm light through a diffraction grating that has slits of equal widths and constant separation between adjacent slits. You expect to see the fourth-order interference maximum at an angle of 66.6∘ with respect to the normal to the grating. However, that order is missing because 66.6∘ is also the angle for the third diffraction minimum (as measured from the central diffraction maximum) for each slit. a. Find the center-to-center distance between adjacent slits. b. Find the...
