Waves

5. the bottom or lowest point on a wave
7. a wave with crests that form of a pattern of straight-line wave fronts
8. the change in the shape of a wave as it passes through an opening or bends around an edge
9. the length of one complete cycle of a wave
12. frequencies that are multiples of a fundamental frequency
15. the lowest natural frequency of a standing wave
16. the top or highest point on a wave
17. the decrease in amplitude of a wave as it passes through a material and loses energy
18. describes a wave with oscillations that are perpendicular to the direction the wave travels
20. an oscillation that travels from one place to another
21. occurs when waves add up to make a larger amplitude
22. a wave with crests that forms a pattern of circular wave fronts

1. describes a wave with oscillations that are in the same direction as the wave travels
2. the pattern of frequency, brightness, amplitude or other wave characteristics that comes from adding waves of the same kind
3. a short duration wave or a single oscillation
4. the bending of a wave as it crosses a boundary between different materials
6. a resonance created by trapping a wave between boundaries that causes the wave to interfere with its reflections
10. an edge or surface where conditions or materials change
11. to spread out or travel
13. states that when more than one wave of the same type is present in a system
14. occurs when waves add up to make a smaller amplitude
19. the bouncing of a wave off of a surface
20. another term for the crests of a wave
