Consider the following statements about sound passing through a gas. A) The pressure of the gas at a point oscillates in time. B) The position of a small layer of the gas oscillates in time.

Question

Philoid · Accepted Answer

Sound waves in a gas propagate due to the oscillation of the pressure at a point. The compressions and the rarefactions move through a point in the gas thus oscillating the pressure at that point, the layer of the gas does not oscillate.

Hence, statement A is correct and statement B is wrong.
