Waves

4. the number of complete waves that pass a particular point in a unit of time
7. a wave in which the medium's particles move in a direction that is perpendicular to the direction of the wave's movement
9. the effect produced by the combination of two or more waves
10. section in a longitudinal wave where the particles are tightly packed together
12. the maximum distance a wave vibrates from its rest position
14. the time it takes two successive wave crests or troughs to pass a given point
16. the bending of a wave because of a change in the wave's speed as it passes from one medium to another
18. the highest point of a transverse wave
19. the distance between a trough and a crest
21. the distance between corresponding points on a wave

1. the conversion of a wave's energy into another form of energy
2. the point where destructive interference causes no displacement
3. the place where constructive interference causes the largest wave
5. a disturbance that transfers energy through matter or space
6. a wave in which the medium's particles move in a circular motion
8. a section in a longitudinal wave where the particles are loosely packed together
11. the bending of a wave around a barrier
13. a wave in which the movement of the medium's particles is parallel to the direction of the wave's movement
15. the bouncing back of a wave after it hits a barrier that does not absorb all of its energy
17. any substance through which a wave can travel
20. the lowest point of a transverse wave
