One of the game developers claimed that it would not be possible for the characters to hear these sounds
because there is no air in
outer space. To explain, she first showed the model below of air particles vibrating
when the computer plays the sound for a person on Earth. In this model, air particles are represented by gray
dots. In the bands marked "A" the particles are vibrating closer together and, in the bands, marked "B" the
particles are farther apart.

3. The graph below shows the relationship between air pressure and the distance that the vibrations
traveled as the sound moved from the computer speaker to the person's ear.
On the graph below:
• Write A on one place that represents how the sound vibrated the air particles in a band marked "A".
Write B on one place that represents how the sound vibrated the air particles in band marked "B".
