Coherent ligh of a wavelength 500nm passes through a narrow slit. In the single-slit diffraction pattern observed on a screen that is 4.0m from the slit, the width of the central maximum is 3.0mm. If the wavelength of the light incident on the slit is change to 400nm, what will the width of the central maximum be?
