Question

An open pipe of length 33 cm resonates with frequency of 1000 Hz. If the speed of sound is 330 m/s, then this frequency is

Easy

A

Fundamental frequency of the pipe
B

Third harmonic of the pipe
C

Second harmonic of the pipe
D

Fourth harmonic of the pipe

Solution

Frequency of p th harmonic
$n = \frac{pv}{2 l} \Rightarrow p = \frac{2 l n}{v} = \frac{2 \times 0 .33 \times 1000}{330} = 2$
