Fig. shows three different modes of vibration of a string of length I.

What is the ratio of frequency between (a) and (c)?

Text Solution

Verified by Experts

If the frequency of the principal note in Fig. (c) is f, the frequency of note in Fig (a) is 3f.
thus ` f_a = 3 f and f_c = f`
Ratio of frequency between (a) and (c) is
` f_a :f_c = 3 :1`
