The tip of the wave.
The higher pressure part of a sound wave is called the compression phase. It represents the regions of increased air pressure created by the vibration of a sound source.
The part of a longitudinal wave with the lowest density is the rarefaction, where the particles are spread apart and the pressure is lower than the surrounding medium.

When particles of a medium are far apart, that part of a wave is called a rarefaction. In a rarefaction, the particles are spread out, resulting in lower pressure and density compared to the surrounding medium.
The particles in a compressional wave are spaced farthest apart at the rarefaction region, which corresponds to the trough of the wave where the pressure and density are lower than normal.
Increased pressure in a longitudinal wave corresponds to the region of compression, where particles are pushed closer together. This region represents the peak of the wave.
The area of a sound wave that represents a compression is the region where the particles are closest together, resulting in high pressure. This is typically seen as the peak or crest of the wave.
The less dense part of a longitudinal wave is called the rarefaction. It is the region where the particles are spread out and have lower pressure compared to the denser region called compression in a longitudinal wave.
The distance between two consecutive peaks or troughs in the wave represents the wavelength of the wave.
The P wave.
The upper part of a wave is called the crest. It represents the highest point of the wave above the rest position.
In rarefactions, particles in a medium become less dense, causing a decrease in pressure and creating regions of lower pressure in the wave. This leads to the spreading out of the wave and a decrease in the amplitude of the wave.
