A string of length L between the two bridges of sonometer wire vibrates in the second harmonic. Its amplitude of vibration is maximum at

A

`L/2`

B

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

C

` L/4 " and " (3L)/4`

D

` L/3 " and " (2L)/3`

Text Solution

Verified by Experts

The correct Answer is:
C
For second harmonic there are two loops. The antinodes are at `L/4 " and " (3L)/4`.
