I was pondering this question and don't know the answer. If one lets a ball drop it bounces. Its frequency slowly increasing as the ball looses energy. If one tosses a rock into a pond, at the point of impact the water oscillates up and down. I assume also at increasing frequency and decreasing amplitude, yes? And now for the real question. If this is so then I assume that the waves spreading out from the point of impact are at decreasing distance. Is this so? Also, what determines the speed of the waves? I am real tempted to get a rock, toss it in to a pond, take a picture and measure the results. -Robert Heckendorn hplabs!hpfcla!robert
