Waves

1. More dense areas of a wave
5. Highness or lowness of a sound.
6. The height of a wave. Measured from rest to crest.
8. Wave Medium moves in the same direction as the energy. Back and forth.
10. Waves Waves that do not need a medium to travel through
11. Interference Two or more waves at the same place at the same time
12. Period of time for one cycle; back and forth movement
14. Wave Particles move at right angles to the direction of the waves energy.
16. Caused by reflection of light waves. ie. an optical illusion
17. Harmonic Motion Back & forth, or repeated motion
18. The matter that waves travel through.
20. Bending of a light wave as it travels through a barrier. The wave will change speed and direction.
21. Waves A combination of transverse and longitudinal wave
22. Effect Change in frequency that is due to motion of a source
23. Highest point in a wave.

2. Producing a wave through a medium
3. Number of seconds per cycle
4. Lowest point of the wave.
7. Distance from one identical point on a wave to another. ie. Crest to crest or trough to trough.
9. Interference two waves come in contact; the result is a wave with a smaller amplitude
13. Interference two waves come in contact; the result is a wave with a larger amplitude
15. Bouncing back of a wave. ie. echo or reflection in a mirror.
16. Waves Waves that need a medium to travel through
19. Number of waves that pass a point in one second.
