Answer:
b. matter
Step-by-step explanation:
Waves disturb matter but do not transmit it.
Waves are disturbances that transmit energy from one point to another. Although they cause disturbances, they do not transfer the matters in the medium.
- Energy is propagated by a wave.
- When for example, sound waves are produced, the disturbance is propagated via particle - particle interaction
- But after the wave train moves, the particles remain.
