Identify the amplitude on the diagram and give the correct description.


C because the wavelength shows amplitude.


C because amplitude is the distance from wave crest to wave crest.


D because amplitude is the distance between a crest (or trough) and rest. 


D because wavelength show amplitude.

Identify the amplitude on the diagram and give the correct description. C because the wavelength shows amplitude. C because amplitude is the distance from wave class=

Verified Answer :

D because amplitude is the distance between a crest (or trough) and rest. 

Answer : The correct option is, D because amplitude is the distance between a crest (or trough) and rest.  

Explanation :

Amplitude : The measurement of the distance of the wave from the rest position of the wave is known as amplitude. Or we can say that, it is the distance between a crest (or trough) and rest position.

It is generally determined by looking on the graph of a wave and measuring the wave's height from the resting position of a wave.

Thus, from the given graph we conclude that D is the amplitude because it is the distance between a crest (or trough) and rest. While C determine the wavelength of the wave.
