1/40,000 sec. is pretty much the shortest flash
duration that occurs when the flash is very close,
lens wide open and not diffusion of any kind.
I guess it is determined by regulating/measuring
electronics, the behaviour of the flash tube itself
(it 'burns' in a curve too, pretty steep flanks,
but still a curve, kinda tailing off).
The longest flash duration is full power of a
single head high power studio flash. That may
comes close to 1/200 sec. (as already stated
in another post).
