Particles in a sound wave don't travel with the wave itself; they oscillate back and forth around their equilibrium position. This is a key difference between sound waves and electromagnetic waves, which are made of oscillating electric and magnetic fields that propagate through space.

Here's a breakdown:

* Sound waves are mechanical waves: They require a medium (like air, water, or solids) to travel.

* Particles vibrate: When a sound wave travels through a medium, it causes the particles in that medium to vibrate back and forth. These vibrations are longitudinal, meaning they occur parallel to the direction of wave propagation.

* Energy transfer: The vibrations transfer energy through the medium, but the particles themselves don't travel long distances. Imagine a row of dominoes falling – the motion is transferred down the line, but each domino stays relatively close to its original position.

Think of it like this:

Imagine a spring with beads attached. If you push one end of the spring, the beads will move back and forth, compressing and expanding the spring. This compression and expansion creates a wave that travels down the spring, but the beads themselves remain in roughly the same place.

Key points:

* The speed of sound: The speed of sound in a medium depends on the properties of that medium, such as its density and elasticity.

* Frequency and pitch: The frequency of the sound wave determines its pitch. Higher frequency waves correspond to higher pitch sounds.

* Amplitude and loudness: The amplitude of the sound wave determines its loudness. Larger amplitude waves correspond to louder sounds.

Let me know if you'd like me to elaborate on any of these points!
