Calculate the frequency of 2nd harmonic in an open organ pipe of length 34 cm, if the velocity of sound is 340 ms -1.

Solution

Sol. In an open organ pipe, the frequency of the second harmonic, $v_2 = 2 \times \frac{v}{2L} = \frac{2 \times 340}{2 \times 0.34} = 1000\ \text{Hz}$ Answer: $1000\ \text{Hz}$
