As a domain expert in physics, I can explain that a compression wave is a type of longitudinal wave where the medium through which the wave is traveling is compressed and rarefied as the wave passes. An
example of a compression wave is a
sound wave in air. When a sound source vibrates, it causes the air molecules to compress and expand in the direction of the wave's travel, creating regions of high pressure (compression) and low pressure (rarefaction). This movement of air molecules allows the sound wave to propagate through the air, enabling us to hear the sound.
