When the particles of a medium displaces due to compression and rarefaction in the direction of the force, it is known as longitudinal waves.
When the particles of a medium displaces due to compression and rarefaction in the direction of the force, it is known as longitudinal waves.
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.
Rarefaction only occurs in a longitudinal wave. Rarefaction is the reduction of the density of a medium. It is the opposite of compression.
a denser medium hav more no.of particles also > the no.of particles > the opposition provided for..... therefore both wavelength and speed of light changes but frequency remains the same.
Rarefraction is part of asound wave where the particles of the medium through which it is travelling are spread out.

The waves that propagate through particles of a medium are mechanical waves (aka waves of vibration).
Why is produced rarefaction and condensation during the sound travelling in the medium?
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.
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.
The particles of the medium will gain some energy. The exact effect will depend on the nature of the wave as well as that of the medium.

slows down in denser mediums & speeds up in less dense ones this explains why ur voice is so high pitched when u inhale a less dense gas like helium & why sound is deep & distorted underwater.
The maximum distance the particles move away from their rest positions as a wave passes through a medium is the amplitude of the wave.
