Coherent light with wavelength 607 nmnm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 mm from the slits. The first-order bright fringe is a distance of 4.84 from the center of the central bright fringe.
a. For what wavelength of light will the first-order dark fringe (the first dark fringe next to a central maximum) be observed at this same point on the screen?
