1. The regions where the coils of a slinky become closer are called compressions. In these regions, the coils are tightly packed together, resulting in an increase in density and pressure compared to the surrounding areas.

  2. The propagation of sound can be visualized by observing regions of varying density or pressure in the medium. Compressions correspond to higher density and pressure, while rarefactions indicate lower density and pressure.

  3. The pressure variations in the medium as sound propagates are determined by the alternating compressions and rarefactions created by the oscillations of particles. Compressions result in higher pressure, while rarefactions lead to lower pressure regions.

  4. Pressure in a medium is related to the number of particles by increasing as the density of particles rises. More particles in a given volume lead to greater collisions, resulting in higher pressure.

  5. Compression in sound waves refers to regions of higher pressure and density, where air particles are closely packed. Rarefaction denotes regions of lower pressure and density, with particles more spaced apart.
