Three wires of identical lengths. Diameters and material are streched on a sonometer box. If their tensions are in the ratio of `1:9:16`. Then their fundamental frequency will be

A

`4:3:2`

B

`1:3:4`

C

`1:9:16`

D

`4:3:1`

Text Solution

Verified by Experts

The correct Answer is:
B
` n propto sqrtT`
` :. N_(1) : n_(2) : n_(3) = sqrtT_(1) : sqrtT_(2) : sqrtT_(3) = 1 : 3 : 4`
