Problem

An open pipe is in resonance in 2nd harmonic with frequency f1f_1. Now one end of the tube is closed and frequency is increased to f2f_2 such that the resonance again occurs in nnth harmonic. Choose the correct option. a. n=3,f2=34f1n=3, f_2 = \frac{3}{4}f_1 b. n=3,f2=54f1n=3, f_2 = \frac{5}{4}f_1 c. n=5,f2=34f1n=5, f_2 = \frac{3}{4}f_1 d. n=5,f2=54f1n=5, f_2 = \frac{5}{4}f_1
