3. a wave in which the vibration of the medium is parallel to the direction the wave travels
6. the unit used to measure frequency
10. the number of complete waves that pass a given point in one second
12. the distance from the midpoint to the crest (or trough) of the wave
13. the interaction between waves that meet
14. A disturbance that transfers energy from place to place
15. a wave in which the vibration of the medium is perpendicular to the direction the wave is traveling

1. interference that decreases a wave's amplitude
2. interference that increases a wave's amplitude
4. the distance between two consecutive peaks or troughs in a wave
5. the bouncing back of a wave when it hits a surface through which it cannot pass.
7. A unit used to compare the loudness of different sounds.
8. the part of a longitudinal wave where the particles of the medium are close together.
9. A wave that requires a medium through which to travel
11. the part of a longitudinal wave where the particles of the medium are far apart
