The maximum number of overtones emitted ...

The maximum number of overtones emitted by an open organ pipe of length 15cm that can be heard by a person with normal hearing (velocity of sound in air is 330m/s ) will be

A

16

B

17

C

18

D

19

Text Solution

Verified by Experts

The correct Answer is:
B
`n=(v)/(2l)=(330)/(2xx15xx10^(-2)) = (330xx100)/(30)`
n=1100 ltbr. Maximum audiable frequency = 20000
Number of harmonics = `20000/1100=18`
Number of overtones = 17.
