Manufacturers of wire (and other objects of small dimensions) sometimes use a laser to continually monitor the thickness of the product. The wire intercepts the laser beam, producing a diffraction pattern like that of a single slit of the same width as the wire diameter. Suppose a helium-neon laser, of wavelength 632.8 nm, illuminates a wire, and the diffraction pattern appears on a screen 2.8 m away. If the desired wire diameter is 1.37 mm, what is the observed distance between the tenth minima on both sides of the wire/central maximum?
