Waves Vocabulary

4. A wave in which the particles of the medium vibrate parallel to the direction of wave motion.
6. The phenomenon in which waves if light of radiation are restricted in direction of vibration.
10. A condition that exists when the frequency of a force applied to a system matches the natural vibration of system.
12. The bending of a wave as it passes from one medium to another.
15. Interference in which individual displacements on the same side of the equilibrium position are added together to form a resultant wave.
17. Position The level of medium when the wave is not in motion.
19. The number of waves that pass a point during a given time.

1. Equals frequency times wavelength.
2. The units of frequency.
3. A frequency shift that is the result of relative motion between the source of sound waves and an observer
5. The distance from the resting position to either the crest or trough.
7. When two waves meet and combine with each other.
8. The turning back of a wave as it hits a boundary.
9. The lowest point of the wave.
11. The distance between a point on one wave to the identical point on the next wave.
13. The spreading of waves into a region behind an obstruction.
14. Interference in which individual displacements on the same side of the equilibrium position are added together to from a resultant wave.
16. A wave at which the particles of the medium move perpendicularly to the direction the wave is traveling.
18. A material (solid,liquid,gas) through which a mechanical wave can transfer energy.
20. The highest point of a wave.
