Wave Puzzle

2. the displacement of a medium caused by two or more waves is the algebraic sum of the displacements caused by the individual waves
5. the change in direction of the wave front at the the boundary between two different media such that the wave returns into the medium from which it originated
9. the number of wave patterns per second
10. waves that cause the particles in a medium to vibrate perpendicular to the direction of the wave
12. the point of zero displacement in a standing wave, produced by the destructive interference of waves
13. waves that causes the particles in a medium to vibrate parallel and perpendicular to the direction of the wave
15. two waves interfere with one another and combine to make a larger composite wave
17. the point of maximum displacement in a standing wave, produced by the constructive interference of wave
18. the process by which a wave spreads out as a result of encountering a narrow aperture or boundary edge

1. maximum displacement from the equilibrium position
3. the pattern created within a medium when the vibrational frequency causes some points in the medium to be standing still
4. two waves interfere with one another and combine to make a smaller compsite wave
6. waves that cause the particles in a medium to vibrate parallel to the direction of the wave
7. distance between points where the wave pattern repeats itself
8. the shortest time interval during the wave pattern repeats itself
11. the change of wave direction at the boundary between two media
14. high point of the wave
16. low point of the wave
