Vibrations and Waves

3. Low points on a wave.
5. A pictorial representation of a wave.
6. the crest of one wave overlaps the trough of another and their individual effects are reduced.
8. the time of a back-and-forth swing of a pendulum.
13. Whenever the motion of the medium is at right angles to the direction in which a wave travels.
15. A repeating disturbance that transfers energy through matter or space
16. the crest of one wave overlaps the crest of another and their individual effects add together.

1. The distance from the midpoint to the crest (or trough) of the wave.
2. this apparent change in frequency due to the motion of the source (or receiver)
4. The bending of a wave around an object
7. Waves that can travel only through matter (sound waves)
9. Matter through which a wave travels
10. The distance from the top of one crest to the top of the next one.
11. The bending of a wave caused by a change in its speed as it travels from one medium to another
12. When the particles oscillate parallel to or along the direction of the wave.
14. The number of vibrations an object makes in a unit of time.
17. High points on a wave.
