- 9. concentration of force
- 10. number of complete wavelengths produced per second
- 11. particle motion that is perpendicular to the wave propagation direction
- 14. maximum variation of a variable from its mean value
- 15. mass per volume
Down
- 1. brighter than normal
- 2. ability to bounce an echo
- 4. the wave that needs a medium to propagate
- 5. more particles together
- 6. effect the principle of converting energy by applying pressure to a crystal
- 7. the combination of transducer, the ultrasound system and the user
- 12. the distance between consecutive corresponding points
- 13. the time it takes for the wave to transition from compression through rarefaction and back to compression
