General Wave

Open Ended

Why do you think the study of waves is important in our daily lives?

A wave is a disturbance that transfer energy (from one place to another) without transferring matter.

The rope wave moves horizontally, the particles of the rope wave vibrate up and down

Sound energy is transferred through the air, but the air (matter) does not move.
