Which restoring force acts on an acoustic wave?
Answer: A
Sound waves are restored by the pressure changes that accompany compression and rarefaction of the air, and they travel at about 340 metres per second near the surface. Buoyancy restores gravity waves, the Coriolis force restores inertial oscillations, and the planetary vorticity gradient restores Rossby waves. Classifying each wave by its restoring mechanism is the most reliable way to keep the whole family straight, since the mathematics of each follows directly from the physics of what pushes the parcel back.
