Energy can be transferred by both waves and particles.

Kinetic energy can be transferred through particle collisions. In low energy particle collisions, one body strikes another body, altering the second body's momentum, and/or deforming one or both bodies. In high-energy particle collision, the kinetic energy of the inbound particle is sufficient to disrupt the stable condition of the impacted particle, atom, or molecule.

Energy is commonly transferred by waves, such as sound and ocean waves. In all such cases, one can argue that any given particle is briefly involved, however it is the waves, not any single particle, that carries the energy over long distances.
.
Light (and all electromagnetic energies) is a special case in which photons behave as both waves and particles. Thus we can argue that, even in this case, energy is transferred by both waves and by particles.
True
In solids, energy is transferred through vibrations of particles called phonons. In liquids, energy is transferred by the movement of particles through convection and diffusion. In gases, energy is transferred mainly through collisions between gas molecules. In a vacuum, energy is transferred through electromagnetic radiation.
Energy and momentum are transferred by water waves. As the water molecules move in a wave motion, they transfer energy from one point to another. This energy transfer creates the movement we observe in water waves.
Mechanical waves can only transfer energy through a medium. These waves require a material medium (solid, liquid, or gas) to travel through, as they rely on the particles of the medium to propagate. Examples include sound waves and water waves.
Some waves can transfer energy only through liquids and solids, but not through gases or vacuum. Some waves, like sound waves, can transfer energy through gases, liquids and solids but not through vacuum. And some waves, notably electromagnetic waves, can transfer energy through vacuum as well as matter.

Non-examples of radiant energy include sound waves, thermal energy transferred through conduction, and mechanical energy generated by moving objects. Only electromagnetic waves, such as light and infrared radiation, are considered forms of radiant energy.
No, mechanical waves transfer energy through a medium (such as air, water, or solids) by causing particles in the medium to vibrate. However, the particles themselves do not travel along with the wave.
Sound wave's transmit energy and not matter because sound travels from particle to particle transferring only energy. That is why when sound travels only the energy travels and the particles just collide with each other but stay in their positions.
Mechanical waves can only transfer energy through a medium because they rely on the vibration and movement of particles in the medium to propagate. Sound waves are an example of mechanical waves that require a medium such as air, water, or solids to travel.
Radiation
Energy is not transferred in the opposite direction of wave propagation because waves transport energy through oscillations or disturbances in a medium. These disturbances can only move in the direction of the wave itself, not against it. In a wave, energy is transferred from one point to another by the movement of the wave particles in the same direction as the wave itself.
There are lots of things they don't transfer.
