Assume that light of a single color, rather than white light, passes through two slits 0.50 mm apart, and an interference pattern is observed on a screen 2.5m away. If the distance from the central fringe to a first-order fringe is measured to be 2.9 mm on the screen, determine the light's wavelength (in nm).
