Match the following:
part a
1. amplitude
2. crest
3. frequency
4. hertz
5. period
6. stiffness
7. trough
part b
a. the low point of a wave
b. the number of oscillations that occur in a given time period
c. the unit for the frequency of a wave; the number of waves per second
d. degree to which a medium resists being compressed
e. the maximum displacement of particles (positive or negative) during wave motion
f. the time required for one wavelength to pass
g. the high point of a wave

Explanation:

In this case, it is required to match the following terms with their definitions.

1. Amplitude : the maximum displacement of particles (positive or negative) during wave motion.

2. Crest : the high point of a wave.

3. Frequency : The number of oscillations that occur in a given time period.

4. Hertz : the unit for the frequency of a wave; the number of waves per second.

5. Period : the time required for one wavelength to pass.

6. Stiffness : degree to which a medium resists being compressed.

7. Trough : the low point of a wave.

The above parameters are the characteristics of a wave. A wave is defined by the above parameters. Hence, this is the required solution.

power out to power in less than 100%

force tends to be low and long diustance masses are high
