Question: An open pipe of length 33 cm resonates with frequency of 100 Hz. If the speed of sound is 330 m/s, then this frequency is
[RPMT 2002]
Options:
A) Fundamental frequency of the pipe
B) Third harmonic of the pipe
C) Second harmonic of the pipe
D) Fourth harmonic of the pipe
Show Answer
Answer:
Correct Answer: C
Solution:
Frequency of p th harmonic $ n=\frac{pv}{2l} $
Therefore $ p=\frac{2ln}{v}=\frac{2\times 0.33\times 1000}{330}=2 $
