What causes the speaker to vibrate?

• The sound makes it vibrate.

• The speaker needs a force such as being plugged in or turned on to cause vibration.

How is energy transferred through the medium?

• The air particles collide into each other over the space between the speaker and the sound detector.

• The speaker sends out energy.

If the sound had a large amplitude, how would the particles move?

• They would vibrate back and forth farther away from the speaker.

• They would vibrate back and forth closer to the speaker.

• They would vibrate back and forth faster.

• They would vibrate back and forth slower.

If the sound had a low pitch, how would the particles move?

• The particles would vibrate back and forth farther from the speaker.

• The particles would vibrate back and forth closer to the speaker.

• The particles would vibrate back and forth slower.

• The particles would vibrate back and forth faster.

Why does the sound detector vibrate?

• It vibrates because the speaker is playing sound.

• It vibrates because the air molecules are pushing on the sound detector.
