Narrow, equally spaced vertical slits with equal widths are located at a distance of D = 2.47 m from a screen. The intensity pattern in the figure is observed when light with wavelength = 570 nm from a laser passes through the slits, illuminating them uniformly. The screen is perpendicular to the laser beam. 3 4 5 6 7 89 cm 7 The number of slits is ... Submit Answer Incorrect. Tries 1/3 Previous Tries Calculate the center center spacing between the slits. Use the cm scale to measure distances on the screen. 2.25x106cm There is a fixed relation between wavelength, slit separation, and angle between the first (or second, third etc) order maximum and the central maximum. The angle can be determined from the distance to the screen and the separation between the first maximum and the central maximum on the screen. Submit Answer Incorrect.
