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