what is the difference between a mechanical wave and an electromagnetic wave?
3. Mechanical waves are caused by wave amplitude and not by frequency. Electromagnetic Waves are produced by vibration of the charged particles. 4. While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance. Mechanical waves are also called elastic waves as their propagation depends on the elastic properties of the medium through which the waves pass.
Mechanical waves need matter to transfer energy, while electromagnetic waves do not, they can travel through space, or a vaccum. Electromagnetic waves include the electromagnetic spectrum...
