waves

2. When a wave comes into contact with a medium and “soaks up” the colors NOT being reflected
4. Waves of light at different frequencies producing different colorsWaves of light at different frequencies producing different colors
7. The number of waves that pass a fixed point in unit time
10. a beam of light or other system of waves is spread out as a result of passing through a narrow space
14. Waves where the particles are distributed perpendicular to the direction of the wave
16. The part in a longitudinal wave where the particles are closest together
20. the change in direction of a wave passing from one medium to another caused by its change in speed
21. Electromagnetic waves with wavelengths longer than visible light but shorter than microwaves
22. disturbance that transfers energy through matter or space
23. Waves where particles are disturbed back and forth parallel to (in the same direction as) the wave
24. The distance between any two corresponding points on a wave, such as from crest to crest or trough to trough

1. The effect is the apparent change in frequency of a wave moving relative to an observer.
3. The highest point of a wave
5. A wave passes through a boundary from one medium to another
6. Electromagnetic waves with wavelengths longer than infrared but shorter than radio waves
8. The vertical distance (height) from its equilibrium point to its crest or trough
9. the return of light or sound waves from a surface
11. An electromagnetic wave of frequency used for long distance communication
12. A substance through witch a wave can travel.
13. Waves that travel through mataves that travel through matterter W
15. Waves of energy that provide us with the visible light spectrum (the colors we see)
17. Waves of energy made by vibrations
18. The area in a longitudinal wave where the particles are farthest apart
19. The lowest part of a wave
