p.8.6 wicor+ vocab 1
what is a medium in terms of waves?
a place where waves cannot travel
a material through which waves travel, like air or wate
the highest point of a wave
the speed at which a wave moves

Explanation:

In wave physics, a medium is defined as a substance (such as air or water) that carries waves. It is not a place where waves cannot travel (as waves need a medium for mechanical waves, except for electromagnetic waves which can travel in vacuum in a different sense but here the context likely refers to mechanical waves). The highest point of a wave is called the crest, and the speed at which a wave moves is wave - speed. So the correct definition of a medium in terms of waves (for mechanical waves) is a material through which waves travel, like air or water.

Answer:

A material through which waves travel, like air or water
