According to the double-slit experiment, when light passes through two slits, it creates an interference pattern on a screen a distance away. The pattern will consist of alternating bright and dark fringes. The intensity of the fringes decreases as you move away from the center, with the brightest fringe being at the center. Therefore, the correct answer is A: The intensity is maximum at the center and gradually decreases to either side.
