1. When a vibrating object moves forward in the air, it compresses the air particles in front of it, creating a region of high pressure known as compression. This initiates the propagation of a sound wave.

  2. The most common medium through which sound travels is air. Sound waves propagate through the air by causing particles to vibrate, transmitting energy in the form of alternating compressions and rarefactions.

  3. Sound waves are classified as longitudinal waves because the particles of the medium oscillate back and forth parallel to the direction of wave propagation, creating regions of compression and rarefaction.

  4. Sound can be visualized as alternating regions of compression (high pressure) and rarefaction (low pressure) propagating through a medium. This creates a wave-like pattern where particles oscillate around their rest positions.

  5. During the propagation of sound in a medium, energy is carried forward. This energy manifests as alternating regions of compression and rarefaction, traveling through the medium as particles oscillate around their equilibrium positions.
