the graphs below describe two waves. the waves are traveling at the same speed. select the graph of the wave…

Explanation:

Step1: Recall wavelength definition

Wavelength is the distance between two consecutive identical - points on a wave (e.g., two consecutive crests or troughs).

Step2: Analyze left - hand graph

Count the distance between two consecutive crests. On the left - hand graph, if we consider the first crest at approximately (x=- 7) cm and the next crest at approximately (x = - 3) cm, the wavelength (\lambda_1\approx4) cm.

Step3: Analyze right - hand graph

On the right - hand graph, if we consider the first crest at approximately (x = 0) cm and the next crest at approximately (x = 4) cm, the wavelength (\lambda_2 = 4) cm. But if we consider the pattern, we can see that the distance between two consecutive crests is larger than in the left - hand graph. The wavelength of the right - hand wave is approximately (8) cm.

Answer:

The graph on the right.
