Seismic waves shake the ground during earthquakes.Light waves travel across the universe,allowing us to see distant stars.And every sound we hear is a wave.So what do all these different waves have in common? A wave is a disturbance that moves energy from one place to another.Only energy is transferred (as a wave moves. The substance that a wave moves through is called the medium. That medium moves back and forth repeatedly,returning to its original position.But the wave travels along the medium.It does not stay in one place. Imagine holding one end of a piece of rope.If you shake it up and down,you create a wave,with the rope as your medium.
