This formula gives the location of the minima of the diffraction pattern, where m is the path difference between the top and bottom rays, and m is an integer. Therefore if m = 5, a minimum will appear on the screen. b) If m = 4.5, it is midway between two minima, so it will result in a bright area on the screen. Q36.02. a) a sin = m . Increasing f will decrease , so the pattern will contract toward the center . b) The corn syrup will decrease , so the pattern will contract toward the center ....
