38. For a string at constant tension, let fn represent the frequency of the nth harmonic (f1 is the frequency of the 1st harmonic, f2 is the frequency of the 2nd harmonic, f3 is the frequency of the 3rd harmonic, and so on). Which of the following equations for fn is consistent with the results of Experiment 1 for String X ?
Your Answer is
Correct Answer is H
Explanation
Observe Table 1 and find that the frequency is proportional to the number of harmonics, and the multiple increases, then the relationship must be multiplication
