Waves

3. The way in which waves travel through a medium.
6. The lowest point of a wave
8. Material through which a wave travels
9. A type of wave where the motion is parallel to the direction of the wave, like a slinky compressing and expanding.
12. Rapid back-and-forth motion, like what happens to create waves.Energy: The ability to do work or cause a change, waves carry energy from one place to another.
13. The highest point of a wave
14. The part of a longitudinal wave where the particles are spread out.

1. How often a wave repeats in a given time, like how many waves pass by in a second.
2. How high or low a sound seems, often related to the frequency of the sound waves.
4. The height of a wave from its middle to the top (crest) or bottom (trough).
5. The part of a longitudinal wave where the particles are close together.
7. A type of wave where the motion is perpendicular, or at right angles, to the direction of the wave, like a ripple on water
10. A repeating pattern that carries energy, like ripples in water or sound in the air.
11. The distance from one point of a wave to the same point in the next wave, like from crest to crest.
15. The ability to do work or cause a change, waves carry energy from one place to another.
