waves

2. longitudinal waves that can only travel through matter
3. highest point on transverse was
10. a wave that can travel only through matter
12. bouncing of a wave off a surface
13. the transfer of energy by a wave to the medium through which it travels
15. passage of light through an object
17. reflected sound wave
18. amount of sound energy that passes through a square meter of space in one second
19. matter where a waves travel

1. change of pitch when a sound source is moving in relation to an observer
4. animal uses to locate an object by means of reflected sounds
5. rapid back and forth motion that can occur in solids,liquids,or gases
6. region of a longitudinal wave where the particles are farthest apart
7. perception of how high or low a sound seems
8. collection of reflected sounds from the surface in a closed space
9. study of how sound interacts with structures
11. system that uses direction of sound waves to find underwater objects
14. distance that transfers energy from one space to another without transferring matter
15. lowest point on transverse wave
16. waves that overlap combine forming a new wave
