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