Mechanical waves use the substrate to move along (the medium). Electromagnetic 'waves' are a combination of a particle and a wave (they have the same properties of both) == photons. Electromagnetic waves encompass light, microwaves, radio waves, and gamma waves (to name a few). Since EM particles act as waves, but also have a mass they actually exist in the Space-Time continuum and can travel without a medium.
