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, the displacement of each coil to the rig smaller maller. as a result, the coils in a compression are squeezed together

Explanation:

Amplitude in a longitudinal wave is the maximum displacement of a medium part. A greater amplitude means more displacement. So, when a wave with greater amplitude moves through the spring toy, each coil is displaced more (displacement is greater). As a result, in a compression, the coils (which are like particles in the medium) are squeezed closer together (more tightly).

Answer:

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