The frequency of fundamental tone in an ...

The frequency of fundamental tone in an open organ pipe of length 0.48 m is 320 Hz. Speed of sound is 320 m/sec. Frequency of fundamental tone in closed organ pipe will be

A

`153.8` Hz

B

`160.0` Hz

C

`320.0` Hz

D

`143. 2` Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_("Closed") = (1)/(2) (n_("open")) = (1)/(2) xx 320 = 160` Hz
