Laser light of wavelength 632.8 nm falls normally on a slit that is 0.0200 mm wide. the transmitted light is viewed on a distant screen where the intensity at the center of the central bright fringe is 8.20 w/m^2 . a)what is the maximum intensity of the bright fringe that occurs immediately before the dark fringe in part (b)? approximate the angle at which this fringe occurs by assuming it is midway between the angles to the dark fringes on either side of it.
