Across
- 5. how many cycles of compression and rarefaction occur per second
- 7. Mechanical energy that is transmitted through a medium by forces acting on molecules.
- 8. propagate by particle motion that is perpendicular to the wave propagation direction
- 9. time required to complete one cycle
- 10. distance wave can travel per unit of time
- 11. works in both medium or vacuum
- 12. propagate by particle compression and rarefaction that results in particle motion that is in the same direction as the wave propagation direction
- 13. distance from one wave peak to another wave peak
Down
- 1. during compression increases, during rarefaction decreases
- 2. combination of the transducer, the ultrasound system and the user.
- 3. maximum variation of a variable from its mean value
- 4. two waves are completely out of phase
- 6. two or more in phase waves in the same physical region
- 9. concentration of force, or force per area
- 14. frequency unit of measure
