Periodic Motion

3. a wave that is not capable of transmitting its energy
4. A disturbance that propagates through a material medium or space
10. the point on the medium that exhibits the maximum amount of negative displacement from the rest position
12. system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration
14. a longitudinal wave propagated by the elastic compression of the medium
15. the shortest distance between two points
16. the horizontal line in the middle of the wave.
17. the spreading of waves around obstacles
19. the time it takes for an object to complete one cycle
20. unit for frequency

1. the change in direction of a wave passing from one medium to another caused by its change in speed.
2. The displacement of the particles of the medium is perpendicular to the direction of the wave
5. The displacement of the particles of the medium is parallel to the direction of the wave
6. One repetition of the motion
7. the maximiun displacement of a particle of the medium from the rest
8. The number of cycles in one second
9. unit for period
11. a property applying to transverse waves that specifies the geometrical orientation of the oscillations
13. the pattern of disturbance caused by the movement of energy traveling through a medium
18. the point on the medium that exhibits the maximum amount of positive displacement from the rest position
