What does frequency represent in a wave?

• It is how often a vibration (cycle) occurs.

• It is a vibration that extends from one place to another.

• It is the distance from one crest to the next.

• It is the distance from the midpoint to the crest or trough.

How is amplitude related to sound?

• As amplitude increases, pitch increases.

• As amplitude increases, pitch decreases.

• As amplitude increases, loudness increases.

• As amplitude increases, loudness decreases.

Which statement below best describes a transverse wave?

• In a transverse wave, particles of the medium move up and down.

• A transverse wave carries the medium with it like an ocean water wave.

• All waves look alike; "transverse" is a label we use for water waves.

• Because of their up and down motion, transverse waves only move in certain directions.

Which statement below best describes a longitudinal wave?

• Unlike transverse waves, the label "longitudinal waves" describes objects that vibrate.

• Unlike transverse waves, longitudinal waves carry particles of the medium along with the wave.

• Longitudinal waves move particles in the medium back and forth, but they leave the particles in about the same place.

• As a longitudinal wave moves through a material, particles in the material move up and down.
