1. A mechanical wave needs a medium for its propagation. An electromagnetic wave can travel through vacuum and it has the highest speed as it moves through the vacuum. Sound wave is a mechanical wave and light is an electromagnetic wave. 2. A mechanical wave can be both transverse and longitudinal but an electromagnetic wave is a transverse wave. 3. The particles of the medium vibrate, when a mechanical wave passes through it. In an electromagnetic wave the oscillating parameters are the electric and magnetic field.
