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.​

Answer:

Look at explanation

Explanation:

One of the easier ways to define wave motion is the continuous movement of particles. When we have a rope for example and whip it, the first particle bumps into the second one then into the third and so on and so forth until the end of the rope. Particles can only move up and down or left and right and the vibration caused by each particle is what sets off the wave motion.
