The fundamental frequency of a closed organ pipe of length `20 cm` is equal to the second overtone of an organ pipe open at both the ends. The length of organ pipe open at both the ends is

A

100 cm

B

120 cm

C

140 cm

D

80 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`20cm=I_("close")`
`(V)/(4(20cm))=(3V)/(2l_("open"))impliesl_("open")=120cm`.
