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 first graph

Count the number of wavelengths in a given distance. For example, from \(x = - 10\) to \(x = 10\) (a distance of \(20\) cm), observe how many full - wave patterns are present.

Step3: Analyze the second graph

Do the same for the second graph. Notice that in the second graph, the distance between consecutive crests (or troughs) is larger.

Answer:

The graph on the right has the greater wavelength.
