In a single-slit diffraction pattern, the central fringe is 320 times as wide as the slit. The screen is 17,000 times farther from the slit than the slit is wide. What is the ratio X/W, where is the wavelength of the light shining through the slit and Wis the width of the slit? Assume that the angle that locates a dark fringe on the screen is small, so that sin is approximately equal to tan .
