Consider a sound wave traveling from left to right in a certain region in air. If, at a particular time and location, the gauge pressure due to the sound wave is a maximum, what can be said about the displacement of the air molecules at that same time and place?
A) it is zero
B) it is maximum to the right
C) it is maximum to the left
D) Cannot be determined
