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