Q: Amplitude describes what about the wave's crest and trough?


Read this paragraph and choose the correct option from the provided answers:

Waves are identified by several characteristics. There is a center line where the medium would be if there were no wave, which is sometimes describes as the undisturbed position. The displacement of the medium above this undisturbed position is called a crest and the displacement below the undisturbed position is called a trough . The maximums of the crest and trough are equal and are called the amplitude . The distance between equivalent positions on succeeding waves is called the wavelength . The wavelength could be measured from a crest to the next crest or from a trough to the next trough, and is commonly represented with the Greek letter lambda, .

 Choices:

- The minimum parts

- How frequently the parts occur

- The width of the parts

- the maximum parts


A:
the maximum parts
