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 wavelength definition

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

Step2: Analyze the two graphs

In the left - hand graph, the distance between consecutive crests (or troughs) is smaller. In the right - hand graph, the distance between consecutive crests (or troughs) is larger.

Answer:

The graph on the right has the greater wavelength.
