As the slit width increases, the diffraction pattern gets narrower and vice versa.
The increase in silt width leads to the narrowing of diffraction pattern of the light because the increase of width reduces the space for the passing of light wave.
So we can conclude that as the slit width increases, the diffraction pattern gets narrower and vice versa.
