vibration vocabulary

4. The distance from the top of one crest to the top of the next one.
5. The distance from the midpoint to the crest (or trough) of the wave.
6. Wave: Whenever the motion of the medium is at right angles to the direction in which a wave travels.
7. Curve: A pictorial representation of a wave.
11. the positions on a standing wave with the largest amplitudes.
13. The number of vibrations an object makes in a unit of time.
15. interference: the crest of one wave overlaps the crest of another and their individual effects add together.
16. Effect: this apparent change in frequency due to the motion of the source (or receiver).

1. Harmonic Motion: the back-and-forth vibratory motion (oscillatory motion), of a swinging pendulum.
2. Wave: When the particles oscillate parallel to or along the direction of the wave.
3. is a regular arrangement of places where wave effects are increased, decreased, or neutralized
8. are the stationary points on a standing wave.
9. Low points on a wave.
10. interference: the crest of one wave overlaps the trough of another and their individual effects are reduced.
12. the time of a back-and-forth swing of a pendulum.
14. High points on a wave.
