Waves Vocabulary

6. a region in a longitudinal wave where the particles are closest together
7. the point on the medium that exhibits the maximum amount of negative or downward displacement from the rest position
8. the maximum amount of displacement of a particle on the medium from its rest position
9. wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave
12. Any electromagnetic wave's frequency multiplied by its wavelength
14. a wave vibrating at right angles to the direction of its propagation.
16. In simple terms, resonance occurs when the driving frequency of an oscillation matches the natural frequency, giving rise to large amplitudes.
17. property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way.
18. the frequency of sound
19. the number of waves that pass a fixed point in unit time
20. The time it takes for two successive crests (one wavelength) to pass a specified point

1. unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds.
2. pattern of disturbance caused by the movement of energy traveling through a medium
3. The frequency with which something (such as a wavelength) occurs, measured in the number of times the cycle repeats during each second of time.
4. a wave that is an oscillation of matter, and therefore transfers energy through a medium.
5. the point on the medium that exhibits the maximum amount of positive or upward displacement from the rest position
10. a state of balance between opposing forces
11. the change in direction of a wave passing from one medium to another caused by its change in speed
13. a wave with a repeating continuous pattern which determines its wavelength and frequency.
15. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
