I cannot seem to visualize how this compression and rarefaction occurs for example when I clap my hands, I know I move air molecules away from me, but it's so weird that such compression(high air pressure) and rarefaction(low air pressure) occurs. I also do not quite understand why this phenomena occurs. Maybe somehow the clap creates a region where there is a high air pressure due to more air molecules leaving the area adjacent to it causing a cascade effect in which the air molecules move in this direction: high<---low, but we also get this direction of air movement low---> high, how does a sound wave continue to cascade the air molecules through space in this high<---low---> manner? I am really confused??? Please, I need help understanding this?
