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.
A second way that waves are characterized is by the types of matter they are able to travel through. Electromagnetic waves (including light) can move through a vacuum. Physical waves require matter through which to propagate. Physical waves are further distinguished by the phases of matter through which they can move.
