Light of wavelength l and frequency f passes through a single slit of width a. The diffraction pattern is observed on a screen a distance x from the slit. Which of the following will decrease the width of the central maximum? (a) Decrease the slit width; (b) decrease the frequency f of the light; (c) decrease the wavelength l of the light; (d) decrease the distance x of the screen from the slit. In each case justify your answer.
