Waves vocab

3. the bending of waves as it passes from one material to another.
11. The “pushing” forces in a longitudinal wave (tight)
12. The “pulling” force in a longitudinal wave (loose)
13. half the vertical distance from the crest to the trough
14. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
17. preventing light from traveling through, and therefore not transparent or translucent
18. all radio waves; microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays.
19. A substance that makes possible the transfer of energy from one location to another
20. Lowest point on a wave

1. Highest point on a wave
2. The particles in a medium vibrate parallel to the direction of the wave.
4. the transfer of the energy of a wave to matter as the wave passes through it.
5. allowing light to pass through so that objects behind can be distinctly seen.
6. the distance from crest to crest or from trough to trough
7. The motion of the particles is perpendicular to the direction of the wave.
8. When two or more waves cross at a point, the displacement at that point is equal to the sum of the displacements of the individual waves.
9. the process of light bending around an obstacle or spreading out after it moves through a small space.
10. Increase or decrease in a frequency of a wave
15. allowing light, but not detailed shapes, to pass through; semitransparent.
16. the number of wavelengths that pass in a given period of time
