C. The highest point in the wave
D. The lowest point in the wave

What part of he wave is labeled with an A.
A. Trough
B. Crest
C. Wavelength
D. Amplitude

What is frequency measured in?
A. period
B. Kilowatt hours
C. hertz
D. joules

What is the definition of period?

B. seconds per cycle
C. cycles per second
D. Number of vibrations

thanks
trust me its worth it to answer 7 points a question.

1) A.

2) C.

3) C.

4) D.

Explanation:

hope it helps you

Explanation:

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.  Therefore it's most likely to be A. The distance from the center of the wave to the crest or the trough.

What is frequency measured in? C. Hertz

The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.

What is the definition of period? D. Number of vibrations

Frequency refers to how often something happens. Period refers to the time it takes something to happen. Frequency is a rate quantity. Period is a time quantity. Frequency is the cycles/second.  A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases.
