The single-slit diffraction pattern shown in the Figure was produced with red light of wavelength lambda = 633 nm. The screen on which the pattern was projected was located a distance D = 2.0m from the slit. The slit has a width of a = 0.30mm. What is the width w of the central maximum? (The width is equal to the distance between the two first diffraction minima located on either side of the center.)
