Rarefraction is part of asound wave where the particles of the medium through which it is travelling are spread out.
What happens to air as you increase your altitude above sea level.
Rarefaction.
RAREFRACTION
the difference is a rarefaction needs vibration i believe i'mnot sure
All sound waves are longitudinal (compression/rarefaction) waves.
When something vibrates, like a loudspeaker, it compresses the air and increases the pressure of the air when it moves out. When the loudspeaker moves in it creates a partial vacum and a decrease in air pressure. The increase/decrease in air pressure is propagated thru the air (or any medium),as a longitudinal wave, by pushing the air in front of it. The part of the cycle which produces the decrease in pressure is called a "rarefacation" of the air.
Rarefaction only occurs in a longitudinal wave. Rarefaction is the reduction of the density of a medium. It is the opposite of compression.
There are no perfect rhymes for the word rarefaction.
When a sound wave travels through air you get a succession of compressions and rarefactions
Rarefaction.
The Answer is rarefaction.
I believe you are referring to rarefaction. The "trough" of a compression / rarefaction wave is called rarefaction.
rarefaction
this kind of wave that includes compressional and rarefaction is called a longitudinal wave.
A rarefaction., in contrast to a compression.
Rarefaction is the reduction of an items density. Rarefaction is the opposite of compression. It is a technique to look at a species richness.
When you have the complete compression and rarefaction of a longitudinal wave, that is one complete wave.
compression
