The medium of a wave is. Select one:

a.
a dashed line indicating the resting position of the wave

b.
where the average position of the wave is located

c.
what the wave is traveling through

d.
the middle point of the wave

I might be wrong but I think C ( what the wave it traveling through). I think C because a wave medium is the substance that carries a wave (or disturbance) from one location to another. The wave medium is not the wave itself and it doesn’t make the wave. It just Carries or transports the wave from its source to other locations.

The matter through which the wave travels is called the medium (plural, media). The medium in the water wave pictured above is water, a liquid.
