Wave Units

3. / the property of sound that varies with variation in the frequency of vibration
6. / the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
7. / any disturbance that transmits energy through matter or space.
9. Speed / the speed at which a wave travels through a medium
10. / a reflected sound wave
12. Boom / an explosive sound caused by the shock wave of an airplane traveling faster than the speed of sound
13. / allowing light to pass through; easily recognized or understood; easily seen through or detected
15. / the combination of two or more waves that results in a single wave
16. Wave / a wave in which the ratio of its instantaneous amplitude at one point to that at any other point does not vary with time
19. waves / waves where the vibrating particles of the medium vibrate perpendicular to the direction of the travel of the wave energy
20. / the number of complete wavelengths that pass a point in a given time

1. / the magnitude of sound (usually in a specified direction)
2. / the maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium
4. Wave / a wave that requires a medium through which to travel
5. Wave / a longitudinal wave that is caused by vibrations and that travels through a material medium
8. / a vibration of large amplitude produced by a relatively small vibration near the same frequency of vibration as the natural frequency of the resonating system
11. / Pertaining to or exhibiting magnetism produced by electric charge in motion
14. / waves passing through a medium
17. Effect / change in the apparent frequency of a wave as observer and source move toward or away from each other
18. / types of matter
