When sound waves interfere to create standing waves, the points on the medium that move up and down with the largest amplitudes are called __________?

Answer: antinodes.

A standing wave is created when two waves in a medium interfere in such a way that certain points along the medium appear to stand still.

Indeed, the points at which the interference between the two waves is completely destructive show no displacement. These points are called nodes.

There are also points at which the interference between the two waves is completely constructive and these points appear to vibrate from a large positive position to a large negative position and back. These points are called antinodes.

The correct answer is: Anti-nodes.

Explanation:

When the interference between the two waves is constructive and the points on the wave that undergo the maximum displacement during each vibrational cycle of the standing wave back and forth. Those points are called anti-nodes. Hence, in the case of sound waves, interference creates standing waves, and the points on the medium that move up and down with the highest amplitudes are called anti-nodes.
