Sound is a wave, not a particle. Sound is a type of mechanical wave that propagates through a medium, such as air, water, or solid objects. These waves are created by the vibration of particles within the medium. When an object vibrates, it causes adjacent particles to vibrate, transmitting the energy of the vibration as a series of compressions and rarefactions through the medium. These compressions and rarefactions form what we perceive as sound.
In a sound wave, there is no movement of particles from one place to another as a whole. Instead, the particles oscillate back and forth around their equilibrium positions, passing the energy along the wave's direction. This is fundamentally different from the behavior of particles in a particle, like in the case of light, where photons behave as both particles and waves (dual nature) according to quantum mechanics.
So, to clarify, sound is a wave phenomenon, and it requires a medium to propagate through, while particles (like photons) can exhibit both wave-like and particle-like behaviors, depending on the specific experiment or context.
