The fundamental frequency of a closed organ pipe is sam eas the first overtone freuency of an open pipe. If the length of open pipe is 50cm, the length of closed pipe is

A

`25 cm`

B

`12.5 cm`

C

`100 cm`

D

`200 cm`

Text Solution

Verified by Experts

The correct Answer is:
B
Closed , Open
`(V)/(4l_(1)) = (V)/(l_(2))`
`l_(2) = 4l_(1)`
`l_(1) = (l_(2))/(4) , = (50)/(4) = 1.25 cm`
