An air column in a pipe, which is closed at one end, will be in resonance with a tuning fork of frequency 200 Hz, if the length of the air column is
[ velocity of sound in air = 320 m/s]

A

30 cm

B

35 cm

C

40 cm

D

50 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`n = V/(4L) :. L = V/(4n) `
` :. L = (320 xx 100)/(4 xx 200) = 40` cm
