Answer:
Waves only transport a portion of energy.
Step-by-step explanation:
Let's think about some examples related to waves in nature:
- An electromagnetic wave is a combination of electric and magnetic fields, both of them oscillate through space and time. That oscillation transport energy, that is bounded in little "packets" of energy called photons. So this wave transmits energy.
- In the case of a solid, the periodic oscillation of the molecules, this kind of oscillation transport energy too and in this particular case it is called phonons. It is just a quantum of energy related to a compression wave, as a sound or a vibration lattice in a crystal.
In conclusion, waves only transport a portion of energy.
