Waves and Energy

1. the interval of time it takes for a motion to repeat.
2. electromagnetic radiation that can be perceived by the human eye.
4. can be used to represent waves
7. the number of occurrences of a repeating event per unit of time.
9. The highest surface part of a wave
11. the subjective perception of sound pressure.
12. lowest part of the wave
14. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another

1. The fundamental frequency, often referred to simply as the fundamental, is defined as the lowest frequency of a periodic waveform.
3. sound navigation and ranging
5. the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound.
6. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
8. a single change from up to down to up, or as a change from positive, to negative to positive
10. a unit of frequency (of change in state or cycle in a sound wave, alternating current, or other cyclical waveform) of one cycle per second.
13. created by energy passing through water, causing it to move in a circular motion
