Question

As a wave moves through a medium, particles are displaced and (2 points)

Answer 1

Answer:A

Explanation:

Particles are displaced and return to their normal position after the wave passes

Answer 2

Answer:

return to their normal position after the wave passes.

Explanation:

When a wave passes through a medium, it displaces particles. The position of maximum displacement is called the amplitude of the wave. How ever, a restoring force acts on the particle. This force is usually directed towards the mean rest position of the particle.

Hence after the wave passes, the particle is restored back to its mean rest position.
