In a Young's double-slit experiment, a set of parallel slits with a separation of 0.144 mm is illuminated by light having a wavelength of 596 nm and the interference pattern observed on a screen 4.50 m from the slits. a) What is the difference in path lengths from the two slits to the location of a second order bright fringe on the screen? ?m b) What is the difference in path lengths from the two slits to the location of the second dark fringe on the screen, away from the center of the pattern? ?m
