Dark fringe physics
WebDark Fringe: discussion In Physics, Dark Fringe is often considered an “Interference fringe” which is bright in colour, mainly formed due to light beams that are present … WebScience Physics In a Young's double-slit experiment, the seventh dark fringe is located 0.029 m to the side of the central bright fringe on a flat screen, which is 1.1 m away from the slits. The separation between the slits is 1.6 × 10-4 m.

WebFigure(2): shows the interference pattern of two light waves to produce dark or bright fringes. Bright fringe(at P) is formed due to the overlap of two maxima or two minima. Figure 2a,2b . Dark fringe(at P) is formed due to … WebWhen the crest of a wave coincides with the crest of another wave then that interference is called the bright fringe. The same thing happens with the dark fringe also, when the trough of one wave coincides with the trough of another wave then results in dark fringes. Overview of Bright Fringes
