An open organ pipe has a fundamental frequency of `300 H_(Z)` . The first overtone of a closed organ pipe has the same frequency as the first overtone of this open pipe . How long is each pipe ? (Speed of sound in air = `330 m//s`)

A

10 cm

B

41 cm

C

82 cm

D

164 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`V//2l_(1) = 300, 2V//2l_(1) = 600 = 3V//4l`,
`l_(2) 3V//600 xx 4 = 41` cm
