In sonometer experiment , the string of length 'L' under tension vibrates iin second overtone between two bridges. The amplitude of vibration is maximum at

A

`L/3, (2L)/3 , (5L)/6`

B

`L/8 , L/4 , L/2`

C

`L/2 , L/4 , L/6`

D

`L/6, L/2 , (5L)/6`

Text Solution

Verified by Experts

The correct Answer is:
D
The string vibrates in its second overtone i.e. its frequency of vibration is 3n.
` :. ` There are 3 loops.

`:. ` The amplitude of vibration is maximum at `A_(1), A_(2) " and " A_(3)`
or at distances `L/6 , L/3 + 4/6 " and " (2L)/3 + L/6`
or at distances of `L/6, L/2 " and " (5L)/6`.
