3. wave- waves that cause the matter in the medium to move up and down or back and forth at right angles to the direction the wave travels
4. reflected sound wave
5. the bending of wave from one medium into another.
7. top of one crest to the top of the next crest, or from the bottom of the trough to the bottom of the next.
8. wave- waves that use a medium to transfer energy
11. effect- source of sound is moving relative to the listener creating a change in frequency.
12. how high or low a sound is
13. when two waves overlap and combine into a new wave.
15. the bending of waves around a barrier.
16. the number of wavelengths that pass a given point in 1 second.

1. wave (longitudinal)- matter in the medium moves forward and backwards along the same direction the wave travels
2. rhythmic disturbance that carry energy without carrying matter.
6. waves- waves that can travel through space where there is no matter
9. the human perception of how much energy a sound wave carries
10. half the distance between the crest and trough. From the resting to point to crest or trough.
14. when a wave strikes an object or surface and bounces off.
