Sound waves and ocean waves are similar in that both

• are longitudinal waves.

• have the same frequency.

• carry energy from one place to another.

• carry a medium from one place to another.

Which generates waves that are capable of traveling through a vacuum?

During a baseball game, fans in the stands create a “wave” by standing up from their chairs when the wave arrives at their location. Which sentence classifies this type of wave and its particle motion?

• It is a transverse wave in which the particles of the wave move in a direction parallel to the wave motion.

• It is a longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion.

• It is a transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion.

• It is a longitudinal wave in which the particles of the wave move in a direction perpendicular to the wave motion.
