Coherent light with wavelength 598 nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 m from the slits. the first-order bright fringe is a distance of 4.84 mm from the center of the central bright fringe
for what wavelength of light will thefirst-order dark fringe be observed at this same point on thescreen?
express your answer in micrometers(not in nanometers).
