Waves

5. when you look in the mirror you see a
6. the unit of frequency
9. an optical image formed by the apparent divergence of rays
10. the rate of occurrence
12. direction of displacement the same a the dirction of propagation
13. a narrow beam of light
16. radiation classified by wavelength
19. point a wave rest at
20. a wave in a medium in which each point on the axis of the wave has an associated constant amplitude
21. the distance measured in direction of propagation of a wave
22. long depression between waves
24. the top of a wave
25. a piece of transparent substance
27. the state of being compressed
28. the state of being ample
31. change of direction in light
32. having a surface that is curved or rounded outward

1. some people have a high
2. the region of maximum amplitude
3. when waves meet and crest line up together
4. curved like a segment of the interior of a circle
7. a point when there is relatively little or no vibration
8. the bending of waves
11. the state of being rarefied
14. the time of a complete cycle of a wave
15. the interference of two waves of equal frequency
17. a wave in which the direction of displacement is perpendicular to the direction of propagation
18. a real picture
23. a single oscillation whose frequency is an integral multiple of the fundamental frequency
26. A substance that makes possible the transfer of energy
29. how loud something is
30. what i look at everyday
