In a Young's double slit experiment, two rays of monochromatic light emerge from the slits and meet at a point on a distant screen, a sin the figure below. The point on the screen where these two rays meet is the eighth-order bright fringe. The dissimilarity in the distances that the two rays travel is 4.04e-6m. What is the wavelength of the monochromatic light?
