What does compression refer to in a longitudinal wave?

• A. The part where waves overlap
• B. The area where particles are far apart
• C. The section of the wave where particles are close together
• D. The segment where the wave is horizontal

Answer: (C)

Compression in a longitudinal wave refers to the section where particles are close together. In longitudinal waves, such as sound waves, the motion of the medium's particles occurs in the same direction as the wave itself. During compression, particles are pushed closer together due to the energy being transferred through the medium, which results in areas of higher pressure. This contrasts with rarefaction, where particles are spread further apart. Understanding this concept is essential as it helps describe the behavior and properties of waves, particularly how they propagate through different media.
