Coherent light with wavelength 591nmpasses through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00mfrom the slits. The first-order bright fringe is a distance of 4.84mmfrom the center of the central bright fringe. 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? Could you please tell me the answer and how to solve it?
