    "Av" and "S" modes immobilze (lock-freeze) the aperture.
    The diaphragm's diameter may not change, but the aperture value changes proportionally to the focal length - regardless of exposure mode.

    All that happens in M or Av mode is that the diaphragm's diameter may remain constant (or close to it for simplicity), the aperture value meanwhile must change as defined by mathematics.

    Oh, did I mention you are an idiot?
