In a Young's double-slit experiment, two rays of monochromaticlight emerge from the slits and meet at a point on a distantscreen, as in the figure below. The point on the screen where thesetwo rays meet is the eighth-order bright fringe. The difference inthe distances that the two rays travel is 3.98*10-6 m. What is thewavelength of the monochromatic light?
