Periodic Motion

2. The displacement of the particles of the medium is perpendicular to the direction of the wave
4. the point on the medium that exhibits the maximum amount of positive displacement from the rest position
6. unit for frequency
10. the maximiun displacement of a particle of the medium from the rest
11. unit for period
14. a wave that is not capable of transmitting its energy
15. the time it takes for an object to complete one cycle
17. the spreading of waves around obstacles
20. the point on the medium that exhibits the maximum amount of negative displacement from the rest position

1. the shortest distance between two points
3. the horizontal line in the middle of the wave.
5. The number of cycles in one second
7. a property applying to transverse waves that specifies the geometrical orientation of the oscillations
8. A disturbance that propagates through a material medium or space
9. The displacement of the particles of the medium is parallel to the direction of the wave
12. One repetition of the motion
13. the pattern of disturbance caused by the movement of energy traveling through a medium
16. system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration
18. the change in direction of a wave passing from one medium to another caused by its change in speed.
19. a longitudinal wave propagated by the elastic compression of the medium
