Answer:
energy
Explanation:
When wave is propagated through a medium then we can say that medium particles are disturbed from their mean position.
All the medium particles start oscillating about their mean position when wave is transmitted through a given medium.
This disturbance created in the medium is known as waves.
So when we disturb one end of medium then this disturbance is propagated into the medium towards other end.
Now this disturbance is basically the transfer of energy along the medium particles.
So in general we can say that the waves is transfer of energy by disturbing the medium particles
So correct answer is
ENERGY
