In a Young's double-slit experiment, a set of parallel slits having a separation of 0.102 mm is illuminated through light having a wavelength of 575 nm and the interference pattern viewed on a screen 3.50 m from the slits.
(i) Determine the difference in path lengths from the two slits to the location of a second order bright fringe on the screen?
(ii) Determine the difference in path lengths from the two slits to the place of the second dark fringe on the screen, away from the center of pattern?
