A) the width of the central diffraction peak increases and the number of bright fringes within the peak increases
B) the width of the central diffraction peak increases and the number of bright fringes within the peak decreases
C) the width of the central diffraction peak decreases and the number of bright fringes within the peak increases
D) the width of the central diffraction peak decreases and the number of bright fringes within the peak decreases
E) the width of the central diffraction peak increases and the number of bright fringes within the peak stays the same
