For a slit of width 
light of wavelength 
when light falls on the slit, the diffraction patterns so obtained as

The first diffraction minimum occurs at the angles given by
From the equation, it is clear that width of the central diffraction maximum is inversely proportional to the width of the slit. On increasing the width size
, the angle 
at which the intensity first becomes zero decreases, resulting in a narrower central band and if the slit width is made smaller, the angle 
increases, giving a wider central band.
