The length of a pipe closed at one end is 33 cm and the speed of sound in air is 330 m/s. What is the frequency of the third overtone produced by the pipe ?

A

`1500`Hz

B

`2000` Hz

C

`1750` Hz

D

`2500` Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`V = 4n l " " :. n = (33000)/(33 xx 4) = 250 ` Hz
For third overtone, frequency is ` 7n = 7 xx 250 = 1750` Hz.
