Waves

2. Units used to measure frequency
4. The distance from the crest to the center of the wave
6. Wave A wave in which the particles of the medium vibrate parallel to the direction of the wave motion
9. The lowest point of a wave
10. The speeding of waves into a region behind an obstruction
13. A condition that exists when the frequency of a force applied to a system matches the natural vibration of a system
14. Interference Interference in which individual displacements on the same side of the equilibrium position are added together form a resultant wave
16. The bending of a wave as it passes from one medium to another
17. The distance between one trough to another or from crest to another
18. Frequency times wavelength
19. The number of waves that pass a point during 1 sec
20. The highest point of a wave

1. The matter through which a wave passes through
3. The turning back of a wave as it hits a boundary
5. The phenomenon in which waves of light or other radiation are restricted in direction of vibration
7. When two waves meet and combine with each other
8. Effect A frequency shift that is the result of relative motion between the source of sound waves and an observer
11. Position The level of the medium when the wave is not in motion
12. Interference Interference in which individual displacements on the opposites of the equilibrium position are added together to form a resultant wave
15. Wave A wave at which the particles of the particles of the direction the wave is traveling
