In a longitudinal wave, the area where particles are spread apart is called

Explanation:
In a longitudinal wave, particles move back and forth in the same direction as the wave travels, creating alternating regions of high and low density. The area where particles are spread apart is called a rarefaction, which is a region of lower density and pressure as the particles are more spread out. This contrasts with the compression region, where particles are crowded together. Density describes how much matter is in a given volume, not a specific part of the wave, and the medium is simply the substance the wave moves through.
