Which of the following best describes how sound moves through air molecules?
- The air molecules remain stationary
- The air molecules vibrate and move like a chain reaction (correct)
- The air molecules move in a circular motion
- The air molecules fly across the space
What does a waveform graph represent in terms of sound?
What does a waveform graph represent in terms of sound?
- The speed of sound in a vacuum
- The frequency of sound waves
- The change in displacement over time of a single air molecule (correct)
- The number of air molecules in a given space
What controls the displacement and speed of sound waves?

Study Notes
- The air is filled with molecules
- Sound from a speaker causes vibrations in the air molecules
- The vibrations move through the molecules like a chain reaction
- The movement of the vibrations can be seen from left to right
- The air molecules themselves are not flying across the space, they are just vibrating
- A waveform graph shows the oscillation of a single air molecule
- The graph represents the change in displacement over time
- The graph maps directly to what is happening with the air molecules
- Amplitude controls the displacement, frequency controls the speed
- The brain processes the vibrations as sound
