Mechanical waves require a medium to travel through. Examples of mechanical waves are sound waves, water waves, a vibrating string. (See related link). Electromagnetic waves â¦ (such as light, radio waves, X-rays, microwaves) do not need a medium to travel through, so these are not mechanical waves.
