In a resonance tube experiment, the first resonating length of air column is 0.2m and second resonating length of air column is 0.62 m, then the inner diameter of the tube is

A

2.33cm

B

3.33cm

C

1.33cm

D

04.44cm

Text Solution

Verified by Experts

The correct Answer is:
B
`e=(l_2-3l_1)/(2) = (0.62-3xx0.2)/(2) = (0.02)/(0.2)`
`e=0.01 therefore 0.3d=0.01`
`therefore d=(0.01)/(0.3) = 0.03333m`
