Across
- 3. A point along a standing wave where the wave has maximum amplitude
- 6. Time
- 9. The largest angle of incidence
- 11. Number of waves pass a fixed point in a unit of time
- 16. Happens when two waves interfere and the maxima of the two waves add together
- 17. Wave A wave in which particles of the medium move parallel to the direction the wave is moving
- 18. The attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave
- 19. Height of wave crest measured from its equilibrium position
- 21. Reflection of waves from a surface
- 23. When one object is vibrating at the same normal frequency as the second object and causes a second object to go into a vibrational motion .
- 24. Measure of the bending of a ray of light when passing form medium into another
- 25. Occurs when maima of two angles are 180 degrees out of phase
Down
- 1. When something changes the direction of a wavelength
- 2. A point along a standing wave where the wave has minimum amplitude
- 4. If a crest of two waves pass the same point of line at the same time they are in phase.
- 5. The highest point in the wave
- 7. Wave that requires a medium to transfer energy
- 8. The angle of reflection is the same as the angle of incidence reflected over the normal
- 10. The change in direction of a wave passing from one medium to another caused by its change in speed
- 12. When one wave is at maximum amplitude and the other is a minimum these two waves cancel each other out
- 13. Spreading of waves around obstacles (bending)
- 14. Change in wave frequency during the relative motion between the wave source and its observer
- 15. A wave where all points oscillate along paths at right angles to the direction of waves
- 20. The lowest point of a wave below the rest position
- 22. Distance between two consecutive waves
