How is amplitude related to sound?

• As amplitude decreases, pitch decreases.

• As amplitude decreases, loudness increases.

• As amplitude increases, pitch increases.

• As amplitude increases, loudness increases.

What does frequency represent in a wave?

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

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

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

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

The number of waves that pass a given point in one second:

• amplitude

• frequency

• period

• wavelength

• frequency

• period

• wavelength

How are frequency and pitch related?

• there is no direct relationship

• higher frequency = higher pitch

• lower frequency = higher pitch

• higher frequency = lower pitch
