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, as in Figure (a). The point on the screen where these two rays meet is the eighth-order bright fringe. The difference in the distances that the two rays travel is 4.57 × 10-6 m. What is the wavelength (in nm) of the monochromaticlight?
