  1. 1. For a wave or vibration, the maximum displacement on either side of the equilibrium (midpoint) position.
  2. 4. The speed with which waves pass a particular point.
  3. 6. The time in which a vibration is completed. The period of a wave equals the period of the source, and is equal to 1/frequency.
  4. 7. One of the places in a wave where the wave is lowest or the disturbance is greatest in the opposite direction from a crest.
  5. 10. The SI unit of frequency. One hertz (Hz) equals one vibration per second.
  6. 11. To cause a wave to move through a medium, to multiply or to breed. To spread out and grow.
  7. 15. A stationary wave pattern formed in a medium when two sets of identical waver pass through the medium in opposite directions.
  8. 17. One of the places in a wave where the wave is highest or the disturbance is greatest in the opposite direction from a trough.
  9. 19. The V-shaped disturbance created by an object moving across a liquid surface at a speed greater than the wave speed.
  10. 20. The pattern formed by superposition of different sets of waves that produces reinforcement in some places and cancellation in others.
  11. 21. The waveform traced by simple harmonic motion, which can be made visible on a moving conveyor belt by a pendulum swinging at right angles above the moving belt.

  1. 2. The shift in received frequency due to motion of a vibrating source toward or away from a receiver.
  2. 3. The distance between successive crests, troughs, or identical parts of a wave.
  3. 5. A wave in which the medium vibrates in a direction parallel (longitudinal) to the direction in which the wave travels. Sound waves are longitudinal.
  4. 8. For a vibrating body or medium, the number of vibrations per unit time. For a wave, the number of crests that pass a particular point per unit time.
  5. 9. A wave in which the medium vibrates in a direction perpendicular (transverse) to the direction in which the wave travels. Light waves and water waves are transverse.
  6. 12. Any part of a standing wave with maximum displacement and maximum energy.
  7. 13. The loud sound resulting from the incidence of a shock wave.
  8. 14. The cone-shaped disturbance created by an object moving at supersonic speed through a fluid.
  9. 16. Phenomenon that occurs when the frequency of forced vibrations on an object matches the object’s natural frequency, producing a dramatic increase in amplitude.
  10. 18. Any part of a standing wave that remains stationary; a region of minimal or zero energy.
