- 8. The lowest point below the rest position
- 10. A wave vibrating at right angles to the direction of its propagation
- 11. The ..... of a wave is the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position

- 5. The distance between any given point and the same point in the next wave cycle
- 6. The displacement of a wave from zero
- 7. The change in direction of a wave passing from one medium to another caused by its change in speed
