Single slit diffraction distance

[labview1958]

What happens to the distance between fringes as the width of the single slit become larger? Does the distance between fringes increases? What happens to the centre bright fringe? Does it become larger with an increasing single slit width? My hunch is: Increasing the width increases the size of the bright central fringe, but applets on the net show otherwise. Can someone help?

If the width of the slit increases, the diffraction pattern becomes more pronounced. It should be otherwise. Do you agree?

If you look at the formula for single slit diffraction you see that at a given wavelength if you increase the size of the slit then the angle at which the minima occur will decrease. Hence we will be able to see further higher order minimas.

Increasing slit width will decrease or increase the distance between fringes?
