A pipe 20cm long is closed at one end. Which harmonic mode of the pipe is resonantly excited by a 430Hz source? Will the same source be in resonance with the pipe if both ends are open? Take speed of sound in air `340m//s`.
Text Solution
Verified by Experts
When both ends are open `n=p(V/(2l))` `rArr p=(2ln)/V` , l=0.2 m Substituting the values we have `p=((2)(0.2)(430))/340` = 0.5 Since p is in fraction the source can.t be in resonance with the pipe
