Question

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

Explanation:

Step1: Recall the definition of amplitude

Amplitude is the maximum displacement from the equilibrium position (the \(x -\)axis in these graphs).

Step2: Analyze the first graph

In the first graph, the maximum displacement from the \(x -\)axis (equilibrium) is \(7\) units (for example, looking at the peaks and troughs).

Step3: Analyze the second graph

In the second graph, the maximum displacement from the \(x -\)axis (equilibrium) is \(2\) units (for example, looking at the peaks and troughs).

Answer:

The first graph (the left - hand side graph) has a greater amplitude.
