Problem: A single slit that has a width of 0.40 mm is illuminated by coherent light of wavelength 500 nm. The diffraction pattern is observed on a screen that is a large distance from the slit. On the screen the width of the central maximum is 4.0 mm. If the width of the slit is changed to 0.20 mm. the width of the central maximum becomes (a) 4.0 mm (unchanged) (b) 2.0 mm (c) 8.0 mm (d) none of these
