A diffraction pattern is produced on a screen 142 cm from a single slit, using monochromatic light of wavelength 490 nm. The distance from the center of the central maximum to the first-order maximum is 3.20 mm. Calculate the slit width. (Hint: Assume that the first-order maximum is halfway between the first- and second-order minima.)
