Here are the solutions to the questions:

7. (b) What is the frequency of this wave?

  • Step 1: Determine the period (T) from the graph. The graph shows displacement versus time. One complete oscillation (one full wave cycle) represents the period. From the graph, one complete cycle takes 2.0 seconds. So, the period T=2.0 sT = 2.0 \text{ s}.

  • Step 2: Calculate the frequency (f). Frequency is the reciprocal of the period:

    f=1Tf = \frac{1}{T} f=12.0 sf = \frac{1}{2.0 \text{ s}}
