Question

Using the diagram below and the labels attached to it answer the following:

Answer 1

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