The data in Part II were analyzed by plotting the maximumsig

The data in Part II were analyzed by plotting the maximum-signal frequencies vs. n to obtain the v_1. Derive the relevant expression using the following information. For a resonant cavity of fixed length L, the resonance condition requires that there be an integral number of half-wavelengths (see Figure 4), or L - n(lambda/2). Also, the speed of sound is just the product of the frequency and the frequency, v_1 = lambda f.

Solution

Data in Part II is not provided in the question. That data is required to study the effects of it on the plot of v_s and further only then concepts of resonance can be applied. Please comment below the required data so that I can provide you with a suitable answer.
