If tension in a wire is made four times, then what will be the change in speed of wave propagationg in it ?

Explanation

We know `v= sqrt ((T)/(mu))`
`implies v prop sqrt T implies (v _(1))/(v_(2)) = sqrt ((T _(1))/(T _(2)) implies (v _(1))/(v _(2)) = sqrt ((T _(1))/( 4 T _(1))`
`implies v _(2) = 2v _(1)`
`implies` Wave speed will become doubled.
