Vibrations and waves

3. A repeating disturbance that transfers energy through matter or space
4. The bending of a wave around an object
6. Waves Waves that can travel only through matter sound waves
8. The number of vibrations an object makes in a unit of time
11. Effect this apparent change in frequency due to the motion of the source or receiver
14. interference the crest of one wave overlaps the trough of another and their individual effects are reduced
16. Matter through which a wave travels
17. Wave When the particles oscillate parallel to or along the direction of the wave
18. The distance from the top of one crest to the top of the next one

1. The bending of a wave caused by a change in its speed as it travels from one medium to another
2. Wave Whenever the motion of the medium is at right angles to the direction in which a wave travels
5. Pattern is a regular arrangement of places where wave effects are increased, decreased, or neutralized
7. High points on a wave
9. interference the crest of one wave overlaps the crest of another and their individual effects add together
10. Curve A pictorial representation of a wave
12. the time of a back and forth swing of a pendulum
13. Low points on a wave
15. The distance from the midpoint to the crest or trough of the wave
