Based on the information presented in the introduction of this problem, what is a sound wave? Based on the information presented in the introduction of this problem, what is a sound wave? Propagation of sound particles that are different from the particles that comprise the medium Propagation of energy that does not require a medium Propagation of pressure fluctuations in a medium

sound is a wave that carries energy and the particles are oscillating around their equilibrium positions.

Explanation:

When the air particles are subjected to a periodic force they oscillate around their equilibrium possessions, this oscillation can propagate in the air creating a sound wave.

Therefore the sound wave is a wave that propagates energy, but the particles have only one oscillation around their equilibrium position.

These waves can be mathematically analyzed as displacement waves and since the oscillation is in the same line of the movement of the wave we can also analyze it as a pressure wave

In summary, sound is a wave that carries energy and the particles are oscillating around their equilibrium positions.
