11. the time it takes for one full wave cycle to pass a point.
12. a disturbance or vibration that transfers energy.
13. interference when two crests meet and make a bigger wave.
15. an area of a wave where pressure is higher.
16. the matter a mechanical wave travels through
19. a reflection where the wave pulse stays upright.
21. wave, a wave where the particles move parallel to the direction the wave travels.
22. a reflection where the wave pulse flips upside down.
25. of phase, when waves do not line up so crests meet troughs.
