Question

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

Explanation:

Step1: Understand the concept of wavelength

Wavelength is the distance between two consecutive crests (or troughs) of a wave.

Step2: Analyze the two graphs

In the left - hand graph, the crests are closer together. In the right - hand graph, the crests are farther apart.
Since wavelength is the distance between consecutive crests (or troughs), the wave with crests (or troughs) that are farther apart has a greater wavelength.

Answer:

The graph on the right.
