Why are sound waves known as mechanical waves?

Hi Parul!

Sound is produced by the vibration of objects. When objects vibrate, it collides with the molecules in the medium. This collision produces mechanical oscillations in the medium. Because of this, sound waves are known as mechanical waves.

Good work @Snehal and @Chandni!! Keep writing!!

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
