Coherent light with wavelength λ = 600 nm falls on a single thin slit and the resulting diffraction pattern is observed on a screen that is 2.0 m from the slit. The width of the central bright fringe is measured to be 4.0 mm. If the width of the slit is doubled while the wavelength of the light remains the same, the width of the central bright fringe in the diffraction pattern
(a) stays the same
