For a given amount of air, pressure DECREASES as volume increases.
And pressure INCREASES as volume decreases. |

Definition
| As tines of fork move out from original position, they push air molecules together, forming areas of high pressure |
|
|
Term
|
Definition
| As tines swing and move back, they allow molecules to move back (and even overshoot their original positions) and this forms less dense areas |

| Explain Pure Tone & Simple Harmonic Motion (SHM) |
|
Definition

this motion produces a sound wave that is a pure tone. (which is periodic motion) |

Definition
These are sounds consisting of 2 or more frequencies, NOT RELATED TO EACH OTHER.
These sound like noise. |

|
Definition
