I am reading in Halliday that the kinetic energy and potential energy carried by a wave in a string are both maximal at y = 0 (equlibrium position) and zero at y = A or r (maximal elongation).
This sounds strange to me because usually KE decreases as PE increases and vice versa. Besides, if at any time both types of energy were zero, shouldn't the wave stop?
