A transverse wave on a string consists of an amplitude A. A tiny spot on the string is colored red. As one cycle of the wave passes by, determine the net distance traveled by the red spot?
By calculating both of the distances PM and MQ, illustrate that PM=QM (This shows that M lies on perpendicular bisector of line segment PQ, but it doesn't show that M actually lies on PQ)
