    Single slit diffraction distance

    from http://www.walter-fendt.de/ph14e/singleslit.htm If the width of the slit increases, the diffraction pattern becomes more pronounced. It should be otherwise. Do you agree?

    Single slit diffraction distance

    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...
