The fundamental frequency of a closed organ pipe is same as the first overtone frequency of an open pipe. If the length of open pipe is `50 cm`, 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_2),=, v/(l_2)),(l_2,=,4l_1):}`
`l_1 = (l_2)/(4) = 50/4 = 12.5 cm`
