How does the amount of energy carried by a wave affect the particles of a medium?

• The particles of a medium vibrate less strongly.

• The particles of a medium vibrate more strongly.

• The particles of a medium come to rest at a farther distance.

• The particles of a medium store more energy after the wave disappears.
