Which statement correctly describes both sound and light waves?

• Light waves travel slower than sound waves.

• Light waves can travel through water, sound waves cannot.

• Light waves can travel through space, sound waves cannot.

• Light waves travel as mechanical waves.

How are light and sound similar?

• They both travel at the same speed.

• They are both waves.

• They are both electromagnetic.

• They both travel through a vacuum.

A student is playing with a small toy boat on a pond. The student throws a rock in the pond. This creates waves that move the boat toward the shore. The boat moves toward the shore because the waves transfer

• energy.

• heat.

• motion.

• water

• seismic waves

• light waves

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.

How are electromagnetic waves different from other waves?

• They have very short wavelengths.

• They transmit energy instead of matter.

• They can travel through a vacuum and through matter.

• They can change direction by reflection when they strike an object.

Which statement correctly describes how a sound wave travels through air?

• The wave carries molecules of air away from the source of the sound.

• The wave carries energy that causes molecules to move back and forth.

• They can travel through a vacuum and through matter.

• They can change direction by reflection when they strike an object.

Sound is able to travel faster in solids than in air because the molecules in a solid are

• closer together than air molecules.

• more easily moved than air molecules.

• moving faster than air molecules.

• larger than air molecules.
