    Mechanical waves require a medium in order to move energy from one location to another. EM waves can operate in a vacuum. The elastic and inertial properties of the medium determine the wave speed for mechanical waves.

    Waves that does not need any medium or matter to travel through, and travels through space, are called electromagnetic waves. Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving.
