Across
- 3. occurs when two waves of the same frequency and amplitude are moving in opposite directions and interfere with each other
- 4. the net effect of the combination of two or more wave trains moving on intersecting paths
- 5. when two waves overlap so that they cancel each other out.
- 7. The time interval of single repetition of a varying quantity of a motion or phenomenon which repeats itself regularly
- 9. the maximum distance moved by a point on a vibrating wave measured from its equilibrium position.
- 10. lowest point on the wave
- 12. change of direction when the wave meets a boundary
- 15. motion in which all points on a wave moves along paths at right angles to the direction of the wave's advance
- 16. the number of waves that pass a fixed point in time
- 17. wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
- 18. the spreading of waves around obstacles
Down
- 1. when two waves overlap so that they combine to create a larger wave
- 2. highest point of the wave
- 6. responsible for the transfer of energy through a medium
- 8. the change in wave frequency during the relative motion between a wave source and its observer
- 11. the length of one wave to another
- 13. substance that transfers the energy
- 14. the change in direction of a wave passing from one medium to another caused by its change in speed
