Using the diagram below and the labels attached to it answer the following: Transverse Wave Anatomy
1. Define the crest and trough of a wave and identify TWO points that represents a crest or a trough.
2. Define wavelength and identify TWO points that could be used in the diagram to measure it.
2. Determine the frequency of this wave if the waves the diagram represents occurred within 1 second.

Answer & Explanation:

Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.

Crest: points A and E

Trough: points C and J

Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.

Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).

I asked that question on my account to answer your question so the people that answerd my question said this is right I HOPE IT IS!!
