Waves

1. Highest point in a wave.
3. Producing a wave through a medium
7. Distance from one identical point on a wave to another. ie. Crest to crest or trough to trough.
8. Wave Particles move at right angles to the direction of the waves energy.
9. More dense areas of a wave
11. Waves Waves that do not need a medium to travel through
15. Period of time for one cycle; back and forth movement
17. Bouncing back of a wave. ie. echo or reflection in a mirror.
18. Harmonic Motion Back & forth, or repeated motion
19. The matter that waves travel through.
20. Interference Two or more waves at the same place at the same time
21. Waves Waves that need a medium to travel through
22. Lowest point of the wave.

1. Interference two waves come in contact; the result is a wave with a larger amplitude
2. Highness or lowness of a sound.
4. Effect Change in frequency that is due to motion of a source
5. Bending of a light wave as it travels through a barrier. The wave will change speed and direction.
6. Interference two waves come in contact; the result is a wave with a smaller amplitude
10. Waves A combination of transverse and longitudinal wave
12. Wave Medium moves in the same direction as the energy. Back and forth.
13. The height of a wave. Measured from rest to crest.
14. Number of seconds per cycle
16. Number of waves that pass a point in one second.
21. Caused by reflection of light waves. ie. an optical illusion
