This is an instructive model of the connection between circular motion, sine wave, and phase velocity. Cylindrically arranged strings carry a spiral arrangement of spheres.
00:25
In the shadow projection, one sees a stationary sine curve. When the cylinder is rotated, a sine wave is seen to propagate to the right or to the left, depending on the direction of rotation.
00:57
Finally, we want to convince ourselves once more that each sphere only moves up and down without propagating along the axial direction.
01:12
Its motion is sinusoidal.
