Where is a place where molecules are far apart?
The Answer is rarefaction.
What is rarefacation?
Rarefaction is the reduction of an items density. Rarefaction is the opposite of compression. It is a technique to look at a species richness.
Does Rarefaction refer to the compression of air molecules?
True.
What is the high pressure area of tightly packed molecules?
Rarefaction
What is the area of compression and rarefaction?
Compression is a Pushing Force whereas Rarefaction is a Pulling Force[Compression is the point when the most force is being applied to a molecule&Rarefaction is the point when the least force is applied].Compression happens when particles are forced/pressed together.Rarefaction is just the opposite,it occurs when particles are given extra space&allowed to expand.Compression&Rarefaction are Effects the wave causes.If you look at any normal visual representation of a Sound Wave,the humps above the middle line are called Compressions,the humps below are called Rarefactions.
What of a sound wave is the distance between a compression or rarefaction and the next compression or rarefaction?
It is equal to wavelength.
What rhymes with rarefaction?
There are no perfect rhymes for the word rarefaction.
Rarefaction occurs only in?
Rarefaction only occurs in a longitudinal wave. Rarefaction is the reduction of the density of a medium. It is the opposite of compression.
Molecules are farther apart in a rarefaction reflection compression or refraction?
Rarefaction.
Where is a place where molecules are far apart?
The Answer is rarefaction.
A region of spread out particles ina compressional wave is called?
I believe you are referring to rarefaction. The "trough" of a compression / rarefaction wave is called rarefaction.
What is the name of the process whereby a material is made less dense?
rarefaction
What is rarefacation?
Rarefaction is the reduction of an items density. Rarefaction is the opposite of compression. It is a technique to look at a species richness.
What types of wave does rarefaction and compression?
this kind of wave that includes compressional and rarefaction is called a longitudinal wave.
What is a part of a compressional wave where the particles are far apart?
A rarefaction., in contrast to a compression.
What is compression and a rarefaction in a longitudinal wave?
When you have the complete compression and rarefaction of a longitudinal wave, that is one complete wave.
What is the opposite of rarefaction?
compression
