Question

The fundamental frequency of air column in a pipe open a both ends is 200 Hz. What is the frequency of the (i) second harmonic (ii) third overtone ?

Answer 1

Hey mate !

can u do Google

Answer 2

Answer:

n(2nd)=3*200=600Hz

n(3rd)=4*200=800Hz

Explanation:

For open pipe,the formula to find frequency at

any overtone is,

n=(p+1)*n(fundamental frequency)
