The fundamental frequency of an open pipe of length 34cm and how many harmonics may be heard by a person having normal hearing ?

A

100Hz, 10

B

300 Hz, 30

C

200 Hz, 20

D

500 Hz, 40

Text Solution

Verified by Experts

The correct Answer is:
D
`n_0 = (v)/(2l) = (340)/(2xx34xx10^(-2)) = 500Hz`
Number of harmonics `=20000/500=40`
