How does the angular width of principal maximum in the diffraction pattern vary with the width of slit ?

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the principal maxima in the resulting diffraction pattern depend on width of the slit?

Light of frequency 25 GHz is incident normally on a rectangular slit of width 4 cm. Calculate the angular width of the central maximum of the diffraction pattern formed by the slit.

What should be the change of angular width of central maximum in a single slit diffraction pattern when Width of the slit is decreased.
