Question

For the propagation of mechanical waves, medium should be continuous and elastic, why?​

Answer 1

Answer:

bcz mechanical waves travels in forms of rarefactions and compressions.....so if there is no continuous medium compression or rarefaction could not occur and the waves cannot travel....

the medium should be elastic so that it could again restore it's original shape after each compressions

Answer 2

Answer:

Mechanical waves are waves that require a medium in order to transport their energy from one location to another. Because mechanical waves rely on particle interaction in order to transport their energy, they cannot travel through regions of space that are void of particles.
