When a pebble is thrown into calm water, waves appear on the surface of the water. These waves depart in concentric circles from where the pebble was thrown. This is the first example of a wave and allows a first definition to be given: a wave is a perturbation that moves.
If a floating cork is placed on water, a small passing wave raises the cork and then puts it back again, but the cork is not swept away by the wave. This example shows that the medium in which the wave propagates is not moving.
There are two types of waves: physical waves that need matter to move (such as a wave that needs water) and electromagnetic waves (such as light).
And sound, is it a physical wave or an electromagnetic wave? Various experiments allow the sound wave to be understood, visualized, and heard.
