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...
An electromagnetic (EM) wave is not a sound wave. A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy. The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields. This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.
