Across
- 3. the time taken for one complete oscillation.
- 5. the top of the wave
- 7. when a wave enters a new medium it bends because the wave changes speed.
- 9. of reflection the angle in which a wave strikes a surface is equal to the angle in which it reflects.
- 11. spaced particles
- 12. wave addition
- 13. the bottom of the wave
- 14. m/s
- 17. angel of reflection
- 19. all of the waves
- 21. bending of a wave around a barrier or through an opening.
Down
- 1. wave subtraction
- 2. 2 mediums
- 4. when a have strike the medium it can not pass through the wave bounces off.
- 6. right angle
- 8. height of the wave
- 10. the distance between 2 waves
- 15. frequency
- 16. mechanical
- 18. packed particles
- 20. wavelength
