This post distinguish Waves as 2 styles:

  1. Longitudinal versus Transverse Waves versus Surface Waves
  2. Electromagnetic versus Mechanical Waves

are there any other distinguishing characteristics?

    $\begingroup$ Dimensionality: 1D, 2D, 3D, etc. For sinusoidal waves: wavelength, frequency, and speed. For non-sinusoidal waves: the waveform and the frequency distribution. Planar vs. spherical vs. other angular distributions. Polarization: planar, circular, etc. Linear vs. nonlinear (e.g., solitons). Scalar wave vs. spinor wave vs. vector wave vs. tensor wave. Real vs. complex (e.g. wavefunction). Number-valued vs. operator valued (e.g., quantum field theory). This is not a complete list but it gives you the idea that waves come in lots of variants! $\endgroup$

    $\begingroup$ BTW, this site doesn’t like “Big List” questions (or answers) so your question might get downvoted or closed, and my comment above might get deleted. PSE wants narrowly focused conceptual questions with one correct answer. $\endgroup$

  • $\begingroup$ @G.Smith Thanks for your reminder. How about this one? Is it a sort of “Big List” question? $\endgroup$

  • $\begingroup$ Yes, it is in my opinion. $\endgroup$
