Question

Which never transfers to a wave

Answer 1

In a strict, linear view of the world, waves simply transfer energy through space or media. But the world is almost never linear, and if one looks closer mass will be set in motion or transported with the wave energy. Examples? Ocean surface waves. Although energy is transported across the surface, one can trace local elliptical transport of water molecules. Also vortex rings. Particles can be trapped within the confines of a vortex ring moving through space.
