Since all EM waves travel at the speed of light, then the spectrum of wavelengths is exactly opposite the spectrum of frequencies. In other words, wavelength and frequency are inversely proportional to each other.
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.
