Is there sound at the bottom of the wave?

When the crack of my split-fingers breaks silence, and the whip hits the air.

It vibrates. 

Is sound at the bottom of the vibration? 

The crest and the trough sweep the air in back-forthed opposition, so that my fingers: could knock on the door of existence.

When I snap my fingers, does the sound make reverb like a drop in the water? 

When it drops to the lowest point, what is there? 

One only knows.
