Why are sound waves known as mechanical waves?

thank u so much guyz

Sound waves are called mechanical waves because they need a medium to travel through.

Electromagnetic waves can travel through space(without medium), whereas sound waves cannot.

Sound waves always do need a medium, the medium can be different like air, water, metal(solid), but the presence of medium is a must for sound waves thats why they are called mechanical waves.

hope its help:)))))))

mechanical waves is a periodic disturbance which required material medium (solid,liquid,gas) for its propogation

example-sound wave in air

that's why sound waves are known as mechanical waves
