In a Young's double-slit experiment, a set of parallel slits having a separation of around 0.102 mm is illuminated through light having a wavelength of 575 nm and the interference pattern viewed on a screen 4.50 m from the slits.
(i) Find out the difference in path lengths from the two slits to the position of a fifth order bright fringe on the screen?
(ii) Determine the difference in path lengths from the two slits to the position of the fifth dark fringe on the screen, away from the center of pattern?
