Across
- 4. number of waves in a time
- 7. the highest point on the wave
- 8. the wave bounces and goes in a new direction at an opposite angle
- 9. The combination of "out of phase" waves the produce a wave with a smaller amplitude
- 10. They have a disturbance perpendicular to the direction of the wave
- 11. the wave bends as it passes through an object due to density of the object
Down
- 1. the distance between the center line and the crest
- 2. the length of one wave crest to crest or trough to trough
- 3. a disturbance that moves across space transferring energy from one place to another
- 5. the lowest point on the wave
- 6. they have a disturbance that is parallel to the direction of the wave
- 7. the combination of "in phase" waves that produces a wave with a bigger amplitude
