If you mean what are the waves called that spread outwards in circles, those are called capillary waves, or ripples.

a slinky spread out and then grab a few coils and release and watch a compressional wave! Another example is a sound wave. the particles compressed together form a compression. The particles more widely spread apart form a rarefaction.slinkySound waveCompressional waves are also called mechanical waves. Examples include the plasma waves or guided waves.
They start from the middle, and spread out equally.

As of being waves, sound waves does just that. They start from origin and spread out. Sound waves will however quickly fade with distance and time.

Sound does not spread out in particles but in waves. Imagine dropping a pebble in a still lake...and that is how sound waves spread out. Sound waves can also reverberate through harder materials; however, soft materials absorb the vibrations.
