Light of wavelength lambda 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. Winch of the following will decrease the width of the central maximum? Decrease the slit width; decrease the frequency f of the light; decrease the wavelength lambda of the light; decrease the distance x of the screen from the slit. In each case justify your answer.
