During sound transmission, what term describes air molecules that are close together?
Correct Answer:
Compression
Explanation:
Compression describes the region where air molecules are pushed close together. Sound travels as a longitudinal wave, with particles oscillating along the direction of travel. In a compression, density and pressure rise because the molecules are squeezed into a smaller space. The wave then alternates with rarefaction, where molecules spread out and pressure lowers. Frequency and amplitude describe how often the wave repeats and how strong the pressure variation is, not the spacing of molecules. So the term for air molecules that are close together is compression.
