Question

another property of a longitudinal wave is amplitude. just as in a transverse wave, the amplitude of a longitudinal wave is the largest displacement of a part of the medium.

the yellow string marks one coil in this spring toy. watch how far the yellow string is displaced to the right or to the left from its starting, or rest, position. that displacement is the waves amplitude.

the amplitude of a longitudinal wave is related to how close together the particles are in a compression. complete the sentences to explain why.

when a wave with ▼ amplitude moves through the spring toy, each coil is displaced farther to the right or left. as a result, the coils in a compression are squeezed together ▼.

Explanation:

Amplitude in longitudinal waves refers to maximum particle displacement. Larger amplitude means each coil moves farther from its rest position. This greater displacement causes coils in compressions to be pushed closer together, making them more tightly packed.

Answer:

When a wave with large amplitude moves through the spring toy, each coil is displaced farther to the right or left. As a result, the coils in a compression are squeezed together more tightly.
