6. A sound wave’s depends on the temperature and state of the medium.
7. Sound travels through solids and liquids because there molecules are closer
together than those in gas.
8. As a medium’s rises, its molecules move faster, conducting sound waves faster.
9. The amount of energy a wave carries corresponds to its .
10. waves are used in medicine to diagnose, monitor, and treat many conditions.
11. human perception of sound intensity.
12. Each unit on a scale that measures sound intensity is a .
13. how low or high a sound seems to be.
14. is the number of compressions or rarefactions of a sound wave that pass per
second.
15. waves have sound frequencies over 20,000 Hz and have medical and other uses.
16. waves with frequencies below 20 Hz usually can't be heard.
17. change in pitch or wave frequency due to a moving wave source.
18. process of locating objects by sending out sounds and interpreting the waves
reflected back.
19. a system that uses the reflection of underwater sound waves to locate objects.
20. What are two medical uses of ultrasonic waves?
21. Over what range of frequencies can a healthy human ear hear sound waves?
