Across
- 2. The distance from the top of one crest to the top of the next one.
- 6. Effect: this apparent change in frequency due to the motion of the source (or receiver).
- 8. are the stationary points on a standing wave.
- 9. interference: the crest of one wave overlaps the trough of another and their individual effects are reduced.
- 12. the positions on a standing wave with the largest amplitudes.
- 15. Wave: When the particles oscillate parallel to or along the direction of the wave.
Down
- 1. High points on a wave.
- 3. Wave: Whenever the motion of the medium is at right angles to the direction in which a wave travels.
- 4. Curve: A pictorial representation of a wave.
- 5. The number of vibrations an object makes in a unit of time.
- 7. the time of a back-and-forth swing of a pendulum.
- 10. Low points on a wave.
- 11. The distance from the midpoint to the crest (or trough) of the wave.
- 13. Harmonic Motion: the back-and-forth vibratory motion (oscillatory motion), of a swinging pendulum.
- 14. interference: the crest of one wave overlaps the crest of another and their individual effects add together.
