A loud buzzer is swinging like a pendulum. An observer is near one end of the buzzer's path, as shown in the image. Which of the following describes and explains what the observer hears as the buzzer moves away from him?

• a lower-pitched buzz than the buzzer's normal sound because the sound waves are arriving less frequently

• a higher-pitched buzz than the buzzer's normal sound because the sound waves are arriving more frequently

• a lower-pitched buzz than the buzzer's normal sound because the velocity of the sound waves is reduced by the velocity of the swinging buzzre

• a higher-pitched buzz than the buzzer's normal sound because the velocity of the sound waves is increased by the velocity of the swinging buzzer
