Across
- 2. Electricity into sound
- 6. mass per volume
- 7. number of cycles of compression and rarefaction per second
- 10. Physical distance from one peak compression to the next
- 11. The principle of converting energy by applying pressure to a chrystal
- 12. The strength, volume or size
- 14. Sound into electricity
- 15. Free from echo
- 16. Refers to the ability to bounce an echo
- 17. A wave that propagates by compression and rarefaction (in same direction as wave propagation direction)
Down
- 1. A wave wherein particle motion propagates perpendicular to wave propagation direction
- 2. concentration of force (force per area), increases in compression, decreases in rarefaction
- 3. Reflect more sound waves producing a brighter appearance (more echogenic)
- 4. A wave that requires a medium to propagate
- 5. Reflect fewer sound waves and appear darker than surroundings (less echogenic)
- 8. Time in which it takes to complete a full cycle
- 9. The rate at which the wave propagates through the medium (Vector Quantity)
- 13. A wave that will propagate in a medium or vacuum
