A pair of parallel slits separated by 1.80 ✕ 10−4 m is illuminated by 503 nm light and an interference pattern is observed on a screen 2.30 m from the plane of the slits. Calculate the difference in path lengths from each of the slits to the location on the screen of a third-order bright fringe and a third dark fringe. (Enter your answers in m.)
