Question

...hey friends...

what are longitudinal waves?? states it's characteristics...

Answer 1

defination:-wave in which the direction of propogation of the wave is the paraller to direction of vibration of partical in the medium is called ss longitudinal wave


characteristics:-1)in longitudinal wave compression and rearfaction are alternately produced
2) in one longitudinal wave compression and rerfaction consist
3) in the region of the wave partical are crowded together is called compression and in the region particals are seprated is called as rerfaction
4) distance between two successive compression or rerfaction is called wave length
5) the longitudinal wave are produced in solid,liquid and gas medium
6) the period and amplitude are same for all particals in longitudinal wave
7) all the sound waves are longitudinal wave


............write answer..............

Answer 2

${Answer :-}$

The waves in which the direction of propagation of the wave is parallel to the direction of vibration of particles of material medium are termed as longitudinal waves.

It is characterised by -
1. In it, compression and rarefaction are alternately produced.
2. They produce increases and decreases in the pressure and hence are also referred to as pressure waves.
3. They are also called compressional waves as they produce compression and rarefaction while travelling through a medium.
4. The direction of propagation of the wave is parallel to the direction of vibration of particles of material medium.
5. It can travel through all the mediums, solid, liquid and gas.
6. In it, the distance between two adjacent compression or rarefaction is wavelength.
7. All the sound waves are generally longitudinal waves.
