Concept:Conduction and wave motion both transfer energy from one point to another without a net movement of the material itself.
Explanation:When a metal rod is heated at one end, the molecules at the hot end vibrate more vigorously and pass kinetic energy to neighbouring molecules.
The molecules do not leave their positions and travel to the cold end.
Only heat energy moves through the rod.
In the same way, a wave carries energy through a medium while the particles of the medium merely oscillate about their mean positions.
The medium itself is not transported along the direction of the wave.
This common feature makes conduction similar to wave motion.
Therefore, the correct option is the one that states that no transfer of materials is involved.
Answer:D. no transfer of materials is involved
