Two similar open organ pipes of length 50 cm and 50.5 cm produce 3 beats per second when sounded together in fundamental nodes. The velocity of sound in air is
Given that, L1=50 cm,L2=50.5 cm
AsL2>L1 so n2<n1
For open pipe, in case of fundamental node
|Why this question?
In open organ pipe resonance occurs when length of the pipe L=nλ2 where n=1,2,..etc
