In a sound wave, the pressure antinodes correspond to displacement nodes. To understand this, we need to delve into the basic principles of sound waves and their properties.
Sound waves are longitudinal waves, which means they propagate in the same direction as the displacement of the medium they're traveling through. In the case of sound, this medium is usually air, but sound can also travel through liquids and solids.

The pressure and displacement aspects of a sound wave are two sides of the same coin. When a sound wave travels through a medium, it causes particles in the medium to oscillate back and forth. This oscillation creates regions of compression (high pressure) and rarefaction (low pressure) in the medium.
Now, let's discuss nodes and antinodes. In a wave, nodes are points of minimum amplitude, or the points where the wave has the least amount of activity. Antinodes, on the other hand, are points of maximum amplitude, or the points where the wave has the most activity.
In the context of a sound wave, a displacement node is a point where the particles of the medium are not being displaced - they're at their equilibrium position. This corresponds to a pressure antinode, a point of maximum pressure fluctuation, because when the particles are at equilibrium, the pressure is at its maximum or minimum.
Conversely, a displacement antinode is a point where the particles are being displaced the most - they're at the peak or trough of their oscillation. This corresponds to a pressure node, a point of minimum pressure fluctuation, because when the particles are at their peak or trough, the pressure is at its equilibrium.
In conclusion, in a sound wave, the pressure antinodes are indeed displacement nodes. This is a fundamental principle of wave mechanics and is crucial to understanding the behavior of sound and other types of waves.
