The length of sonometer wire is doubled...

The length of sonometer wire is doubled and the tension is increases four times. The frequency will

A

become twice

B

be reduced to one half

C

remain the same

D

become on third

Text Solution

Verified by Experts

The correct Answer is:
C
`n_(2)/n_(1) = L_(1)/L_(2) sqrt(T_(2)/T_(2)) = 1/2 xx sqrt(4/1) = 1/2 xx 2 = 1`
` :. n_(2) = n_(1)`
