Question

The ratio of frequency of fundamental notes produced by an open pipe and a closed pipe of same length is

Answer 1

Answer:1:2

Fundamental Frequency of open pipe = v/4l

Fundamental frequency of closed pipe =v/2l

n1 /n2 = v/4l ×2l/v

As velocity in air v and length are equal so they will cancel each other and we get

n1:n2 =1:2

I hope this is the answer
