Labels:text | screenshot OCR: In Leonardo's investigations of how waves interact as they roll into one another, he experiments with two and three waves created at the same time. In each case, he observes that "water is of such agility that the motion of any wave, be it at the bottom, in the middle, Demonstrate or above, will never be hindered by the motion of another wave which were to come its way." (14v) As this animation demonstrates, his experiments show that as each wave extends, or "propagates," through the others, it has almost no effect on them.
