Single Slit Fraunhofer Diffraction - Curve of intensity

In the curve of intensity of the single slit Fraunhofer diffraction, the intensity I is maximum at the center O of the central bright fringe. The intensity decreases as one moves from O in both directions of the sinθ axis until it vanishes completely at the centers of the first dark fringes. The intensity increases again until it reaches a new maximum at the centers of the first bright fringes and so on.
The intensities at the centers of the bright fringes are much less than that at the center of the central bright fringe, and these intensities decrease as one moves away on both sides of the central fringe.
