Vibrations and Waves Vocab

2. Pattern: is a regular arrangement of places where wave effects are increased, decreased, or neutralized
6. interference: the crest of one wave overlaps the crest of another and their individual effects add together.
8. the time of a back-and-forth swing of a pendulum.
10. The distance from the top of one crest to the top of the next one.
12. Low points on a wave.
14. Wave: Whenever the motion of the medium is at right angles to the direction in which a wave travels.
16. The distance from the midpoint to the crest (or trough) of the wave.

1. High points on a wave.
3. Wave: When the particles oscillate parallel to or along the direction of the wave. to or along the direction of the wave.
4. Effect: this apparent change in frequency due to the motion of the source (or receiver).
5. Curve: A pictorial representation of a wave.
7. The number of vibrations an object makes in a unit of time.
9. interference: the crest of one wave overlaps the trough of another and their individual effects are reduced.
11. are the stationary points on a standing wave.
13. the positions on a standing wave with the largest amplitudes.
15. Harmonic Motion: the back-and-forth vibratory motion (oscillatory motion), of a swinging pendulum.
