Assuming that you are referring to longitudinal waves, the area where particles are closest together would be called the "compression" area. The "rarefaction" is the opposite; this is where the medium is least dense.
Sound is a good example of longitudinal waves. If you look closely at a speaker cone, you be able to see that they seem to move in and out very rapidly. This is what "pushes" and "pulls" the air molecules and creates compressions and rarefactions which our ears receive and transmit as a neural impulse to our brain, allowing us to hear.
Although transverse and longitudinal waves are both different types of waves, they are dissimilar (particles in a transverse wave move perpendicular to the motion of the wave (up and down) where as particles in a longitudinal wave move in the direction the wave is traveling).
A compression?
longitudinal waves cUSED BY AN EARTH QUAKE ARE CALLED
Compression is the part of a longitudinal wave where the particles of the medium are crowded together. Rarefaction is the part where the particles are spread apart.
No, particles of the medium do not become part of the wave
I
A Transverse Wave
when the particles of the medium are far apart, that part of the wave is called a?
frequency
Crest is the highest point for the Transerve wave. Trough is the lowest point of the Transerve wave. Compression is the part of the longitudinal wave where the particles are croweded. Rarefraction is the part of the longitudinal wave where the particles are spread aprat.
compression
Ok
Compression is the areas where the particles are closer together. Rarefaction is the areas where the particles are stretched apart.
As a sound wave travels it compresses the air particles around it together in order for it to travel because a wave cannot travel if the matter it uses isn't connected.
1. A compression wave is when the particles in a wave are close together and not spread out. 2. A compression wave is where the pressure in the waves is higher than atmospheric pressure in that particular area where the particles come together.
