A pipe 30 cm long, is open at both ends. Which harmonic mode of the pipe resonates a 
kHz source?
(speed of sound in air = 330 m s –1 )
Text Solution
Verified by ExpertsThe correct answer is:
B
Here,
Speed of sound, v = 
Length of pipe,
In a open pipe (open at both ends), the frequency of its 
harmonic is
