Sound Waves & Energy

2. a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
8. indicates how much energy the wave is carrying.
9. power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
11. location without transporting matter.
13. a type of wave; the direction in which the wave travels is perpendicular to the direction of the disturbance.
14. can be calculated if the frequency and wavelength are known.
15. the distance from its crest to its trough.

1. a type of wave that travels in the same direction as the disturbance that formed it.
2. the energy present in a sound wave.
3. the distance between crests or between compression.
4. a disturbance that travels through a medium, transporting energy from one location (its source) to
5. the number of waves passing a fixed point in a given amount of time (usually per second).
6. the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
7. relating to the interrelation of electric currents or fields and magnetic fields.
10. degree of loudness.
12. the time it takes for one complete wave (that is, one crest plus the adjacent trough) to pass a given point.
