Across
- 7. The lowest point on a wave
- 8. Frequency (high-low)
- 10. cone shaped, happens when objects move faster than the speed of sound
- 11. (T) The time that it takes to complete one complete cycle
- 12. Displacement perpendicular to wave direction (ocean light)
- 13. Sharp crack hear when a shock wave arrives
- 14. The height of the wave
- 16. forcing something to vibrate
- 17. molecules close together (crest) (up pressure)
- 19. (f) How often or how quickly a wave passes by
- 20. frequency shift due to motion
- 21. The length from one crest to the other
Down
- 1. molecules far apart (trough) (further down trough)
- 2. appear to not be moving along the medium
- 3. displacement II to wave direction (sound)
- 4. 20-20,000 Hz
- 5. (m/s) How fast the wave was moving (V=f*Lambda)
- 6. When two waves overlap and make a smaller wave
- 9. The highest point on a wave
- 15. When two waves overlap and make a bigger wave
- 18. metal with two stakes that vibrates when hit together
