Sound propagation can be visualized as the propagation of density or pressure variations in the medium.

Pressure is related to the density of particles in a medium. More density results in higher pressure, and vice versa.

Compression refers to the region of high pressure, while rarefaction refers to the region of low pressure.

The rapid movement of the object creates compressions and rarefactions in the air.

Work is defined as the magnitude of the force applied to an object multiplied by the distance the object moves in the direction of the force. Mathematically, work (W) = force (F) × distance (d) moved in the direction of ...
