Waves

1. (a vector arrow, drawn perpendicular to the wave front, that indicates the direction in which a wave is moving)
2. (the "actual" wave - easy to see with a water wave.)
4. (The more energy a wave has, the ___ is its amplitude)
8. (___ waves move particles parallel to the direction the wave is moving, “push-pull” waves.)
10. (time required to go through one cycle. Measured in seconds)
12. (interference- Occurs when the crest and troughs of two interfering waves meet, and their amplitudes cancel out.)
13. (Increasing the frequency of a wave ___ its wavelength.
15. (Waves near shore will break and carry the medium with it, which is why __ washes up on shore)
16. (interference is when the two interfering waves met in the medium and have displacement in the same direction.)
18. (___ waves Travel on a surface separating 2 media)
19. (how fast the wave is moving)

1. (is when a mechanical wave strikes a barrier.)
3. (____ waves cause the medium to vibrate at right angles to the direction the wave travels)
5. (the material through which a wave passes)
6. (max displacement from its rest position (also known as wave height))
7. (____ of incidence- the angle formed by the ray and the surface it hits)
9. (distance between two identical points on consecutive waves)
11. (number of cycles in a certain time.)
14. (when energy moves through a medium as a vibration)
17. (wave ___ is the phenomenon that takes place when waves while traveling in the same media met.)
