Answer:
Experiment to show that in a wave motion, only energy is transferred, but particles of the medium do not move: ... If we place a piece of cork on water surface at some distance away from the point where the stone strikes it, we notice that cork does not move ahead, but it vibrates up and down, while the wave moves ahead.
Answer:
The following is the experiment:
When a stone is dropped in still water of a pond, the sound of a stone striking the water surface is heard, which is actually a disturbance produced in water at the point where the stone strikes it. The disturbance propagates radially outwards, in all directions in the form of circular waves on the water surface.
If a piece of cork is placed on the surface of water at a distance away from the point where the stone strikes it, it is observed that the cork does not move forward, but it vibrates up and down, the wave still moves ahead. It is because water particles begin to vibrate upwards and downwards at the same point where the stone strikes. These particles then transmit their energy to the adjacent particles causing them to revert to their mean positions. Hence, particles do not move but only transfer energy to other particles.
