it happens during the trough
The compression or crest of a sound wave has molecules that are tightly packed together, which leads to higher pressure and increased density compared to the rarefaction part of the wave.
A heartbeat has two parts the first part in the flow of the blood into the heart. The second part is the flow of the blood out of the heart. That is why heart beat is a bub-bub sound.
During the S stage DNA synthesis occurs. (copying of the DNA)
It depends on what part of the world you live in.
The part of a wave where molecules are pressed close together is called compression. This is an area of high pressure in the wave where the particles are densely packed.

The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
compression
Sound waves that are compressed are made of (air) molecules that are more densely concentrated - that is (ie) more molecules are packed into the space of the compressed wave than there are in the (same) space of the surrounding expanded waves.
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 sound wave where particles are bunched together is called compression. This is the region where air particles are pushed close together, creating an area of higher pressure.
Rarefaction is the part of the sound wave where the air particles are the farthest apart from each other. It's like the "trough" of a transverse wave. The size of this part affects the wavelength and amplitude of the sound produced, which changes the volume and pitch. Note that there's also another part of the wave called "compression". This is like the "peak" of a transverse wave.
A region of high pressure in a sound wave is called compression. This is the part where air particles are pushed closer together, resulting in higher pressure.
There is no separate compression stroke on a 2 stroke engine, but there is compression - the intake and compression take place on the same staroke, the intake on the first part and compression on the later part.
In terms of particles, "compression" means that particles move closer together.
A heartbeat has two parts the first part in the flow of the blood into the heart. The second part is the flow of the blood out of the heart. That is why heart beat is a bub-bub sound.
Rarefaction is the less dense part of a compression wave where the particles are spread apart.
