1. The propagation of disturbance in a slinky can be compared to sound propagation in a medium because both involve longitudinal waves, where compressions and rarefactions travel through the medium, and particles oscillate back and forth parallel to the wave's direction, without moving permanently.

  2. In longitudinal waves, particles of the medium oscillate back and forth about their rest positions. They move parallel to the direction of wave propagation, creating regions of compression and rarefaction, but do not undergo any net displacement from their original positions.

  3. Sound waves propagate in a medium through a series of compressions and rarefactions. These alternating high and low-pressure regions move through the medium as particles oscillate back and forth parallel to the wave's direction, transmitting the sound energy without a net movement of particles.

  4. In a slinky, compressions are regions where the coils are close together, while rarefactions are regions where the coils are spread apart, mimicking the high-pressure and low-pressure areas of sound waves.

  5. The most common medium through which sound travels is air. Sound waves move through the air by causing particles to vibrate, creating compressions and rarefactions that transmit the sound energy.
