Across
- 3. The number of waves per unit time
- 7. interference Occurs when identical waves are superimposed exactly out of phase
- 9. wave Disturbance parallel to propagation direction
- 11. boom Constructive interference from object faster than sound
- 13. Occurs when driving force matches natural frequency
- 15. wave A wave with only one crest or a few crests
- 17. Distance between adjacent identical parts of a wave
- 18. effect Shift in observed frequency due to motion of source or observer
- 19. Causes a wave to change direction
- 20. wave A wave produced by superposition that does not propagate
Down
- 1. Causes a wave’s path to bend when changing medium
- 2. wave A wave that repeats for several cycles
- 4. interference Occurs when identical waves are superimposed exactly in phase
- 5. A disturbance that moves and carries energy but not mass
- 6. The time for one complete wave cycle
- 8. wave Disturbance perpendicular to propagation direction
- 10. Location of maximum amplitude of a standing wave
- 12. wave Must travel through a medium
- 14. Points where there is no motion in standing waves
- 16. The combination of two waves at the same location
