Wave, Sound, and Light

2. Lens a lens that is thicker at the edge than in the middle
5. Spectrum the range of all types of EM waves
6. the highest surface part of a wave
11. the number of times the pattern repeats in a given time
12. a material in which a wave travels
13. transparent object with at least one curved side that causes light to change direction
14. a material through which light does not pass through
15. a material that allows most of the light, but you cannot see through clearly
17. the maximum distance that the wave moves from its rest position
19. the distance between one point on a wave to the same point on the next wave
20. the passage of a wave on its surface

1. the transfer of energy tat is absorbed by a barrier
3. Lens a lens that is thicker in the middle than on the edges
4. the change in direction of a wave as it changes speed while moving from one medium to another
7. Waves a wave that travels only through matter
8. a material that allows almost all of the light striking it to pass through, and through which objects can be clearly seen
9. the change in direction of a wave when it travels by the edge of an object or through an opening
10. bouncing of a wave on its surface
16. Filters a photographic filter that absorbs light of certain colors
18. a piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light
