1. In Physics, we distinguish between wave motion and particle motion Wave motion
refers to the movement of a wave-like pattern from one location on the medium to
another. When you view a water wave moving along the surface of water, you are
observing wave motion. There is a very obvious movement of a collection of crests and
troughs along the water surface. In the Simple Wave Simulator, there is a collection of
crests and troughs moving through a rope this is wave motion. But there are also three
points on the rope that are colored red. When you observe the motion of these points.
you are observing particle motion - the motion of particles of the rope. Describe the
motion of these particles.
