Waves

2. (a vector arrow, drawn perpendicular to the wave front, that indicates the direction in which a wave is moving)
4. (Increasing the frequency of a wave ___ its wavelength.
6. (the "actual" wave - easy to see with a water wave.)
10. (___ waves move particles parallel to the direction the wave is moving, “push-pull” waves.)
13. (distance between two identical points on consecutive waves)
14. (wave ___ is the phenomenon that takes place when waves while traveling in the same media met.)
17. (___ waves Travel on a surface separating 2 media)
18. (The more energy a wave has, the ___ is its amplitude)
20. (how fast the wave is moving)

1. (is the change of direction, or bending, of waves when they move between mediums.)
3. (max displacement from its rest position (also known as wave height))
5. (____ waves cause the medium to vibrate at right angles to the direction the wave travels)
7. (interference is when the two interfering waves met in the medium and have displacement in the same direction.)
8. (____ of incidence- the angle formed by the ray and the surface it hits)
9. (the material through which a wave passes)
11. (interference- Occurs when the crest and troughs of two interfering waves meet, and their amplitudes cancel out.)
12. (number of cycles in a certain time.)
15. (time required to go through one cycle. Measured in seconds)
16. (when energy moves through a medium as a vibration)
19. (is when a mechanical wave strikes a barrier.)
20. (Waves near shore will break and carry the medium with it, which is why __ washes up on shore)
