Question

what is the medium for the wave? the people rope air

Explanation:

In a wave, the medium is the substance through which the wave travels. Here, the wave is on the rope (as shown in the image with two people holding a rope with a wave pattern), so the medium for this wave is the rope. Air is not the medium here (as it's a rope wave, not a sound wave in air), and "the people" are the sources of the wave's disturbance, not the medium.

Answer:

rope
