[@suparnamukherjee8388]

Ma'am, how are the contraction and rarefaction related to the ups and downs of the waves

[@VedantuJunior]

That's a very good question. Whenever there is a contraction it is the crest (up) and when there is a rarefaction it is trough (down). The contraction and rarefaction is depicted as a wave.

[@arushclinic5977]

Thanks mam to clear my bouts

[@ayishapandith4058]

There are 2 types of wave i.e, transvers wave n longitudinal wave... In case of transverse wave... They travel through crust n trough Crush - highest place a wave rises Trough- lowest position a wave sinks In case of longitudinal wave.... They travel by means of contraction n refraction Contraction-a place where particles are much closer. Here the density is high but volume is low Refraction - a place where particles are far away from each other. Here the density is low but the volume is high...

[@ayishapandith4058]

Sorry its not contraction... Its compression* i.e, region of high pressure
