Cool. So if it was a string instead of a column of water, it would just be an unmoving straight line (or points equidistant from the speaker), depending on where it was in the cycle it was captured by the strobe.




I may have misunderstood, I think you already know what I was trying to explain?

I beleive the water stream is not in the same direction as the sound wave would be,
but at right angles to it. If the stream (or a string) were in the same direction as
the soundwave from the speaker, both would remain straight.

I think that is what you meant?
