c) adjacent slits separated by a distance d. Light of wavelength A is incident on the slits and observed on a screen a distance L beyond the barrier. How wide are the bright fringes on the screen? The width of a fringe is defined as the distance (a length, not an angle) between the points of zero intensity on either side of the fringe on the screen.
