Challenging Questions

Q1: Where does the greatest pressure occur?

A1: During compression, the molecules of the medium are forced together, resulting in the increased pressure and density. During expansion the molecules are forced apart, resulting in the decreased pressure and density. This coincide with the points of permanent zero amplitudes which are also called nodes. Refer to the simulations as N, nodes.
