  1. 2. Waves: Waves that can travel only through matter (sound waves)
  2. 6. Pattern is a regular arrangement of places where wave effects are increased, decreased, or neutralized.
  3. 7. The bending of a wave around an object
  4. 8. the time of a back-and-forth swing of a pendulum.
  5. 9. Low points on a wave.
  6. 12. The bending of a wave caused by a change in its speed as it travels from one medium to another
  7. 13. Matter through which a wave travels
  8. 14. The distance from the midpoint to the crest (or trough) of the wave.
  9. 16. The number of vibrations an object makes in a unit of time.
  10. 17. Wave: Whenever the motion of the medium is at right angles to the direction in which a wave travels.
Down
  1. 1. Curve: A pictorial representation of a wave.
  2. 3. High points on a wave.
  3. 4. interference: the crest of one wave overlaps the crest of another and their individual effects add together.
  4. 5. Wave: When the particles oscillate parallel to or along the direction of the wave.
  5. 7. Effect: this apparent change in frequency due to the motion of the source (or receiver)
  6. 10. A repeating disturbance that transfers energy through matter or space
  7. 11. The distance from the top of one crest to the top of the next one.
  8. 15. interference: the crest of one wave overlaps the trough of another and their individual effects are reduced.
