The end correction of a resonance column...

The end correction of a resonance column is 1 cm. If the shortest length resonating with the tunning fork is 10 cm, the next resonating length should be :

A

32cm

B

40cm

C

28cm

D

36cm

Text Solution

Verified by Experts

The correct Answer is:
A
For First resonance `lamda/4=l_1+e=11cm`
For second resonance `, (3 lamda)/4=l_2+e`
`implies l_2=3 times 11-1=32 cm`
