Wave Basics

2. time to complete 1 oscillation (measured in seconds)
5. disturbance that moves energy through a medium vacuum from one location to another
10. the height of the wave, measured from equilibrium; greater Amplitudes transfer more energy
13. region of low concentration of particles in longitudinal waves (low pressure). (looks "stretched")
16. region of high concentration of particles in longitudinal waves (looks "squeezed")
19. a wave capable of transmitting energy through a vacuum.
20. an oscillation; a repeating back-and-forth motion about an equilibrium position
21. a wave in which particles move in a direction parallel to the wave movement with compressions and rarefactions

1. a wave in which the particles move in a direction perpendicular to the direction of the wave motion with crests and troughs
3. natural or resting position of the medium. The state of the medium if there was no disturbance or energy it input
4. distance between successive crests, troughs, or identical parts of a wave (λ)
6. frequencies above 20,000 Hz, the upper limit of human hearing.
7. a pressure wave which is created by a vibrating object that propagates as a longitudinal through a medium such as a air
8. unit of measure for frequencies number of oscillations in 1 second
9. frequencies below 20 Hz, the lower limit of human hearing.
11. a wave that requires a medium to travel and is not capable of transmitting its energy through a vacuum.
12. part of a wave that is lowest where the disturbance is greatest in the opposite direction of the crest.
14. the number of full oscillations that pass a particular point per unit time
15. part of the wave that is highest, here the disturbance is greatest.
17. the amount of energy transported past a given area of the medium over time; in sound this is perceived as loudness
18. a substance or material that carries the wave/that the wave travels through
