Physics Waves

3. waves moving perpendicular to the wave direction
5. low density, particles spaced further apart
7. to move
8. acoustic variable, heating or cooling of tissue
9. strength of the wave, maximum variation of the wave
11. acoustic variable, particle motion
12. substance a wave needs in order to propagate.
15. the physical distance on one cycle
18. example of longitudinal, mechanical wave.
19. how many times an event occurs per time
20. how frequency and period are related
22. when waves are added together to make a bigger wave
23. high density, particles closely spaced together
24. a wave movement through compression, rarefaction and back to compression

1. to move or oscillate
2. when waves are out of phase, and waves are cancelled out
4. changes to the medium due to wave travel
6. time it takes for a cycle
10. velocity determined by the medium only
13. acoustic variable,continuous physical force exerted on or against an object by something in contact with it.
14. acoustic variable, mass per volume
16. distance sound can travel per unit of time
17. wave that move by areas of compression and rarefaction
21. a wave that needs a medium
