If tension in a wire is made four times, then what will be the change in speed of wave propagationg in it ? |
|
Answer» Solution :Wave speed in the wire is `v= sqrt ((T)/(mu))` `THEREFORE v prop sqrtT implies (v _(1))/(v _(2)) = sqrt ((T _(1))/(T _(2)))` `therefore (v _(1))/(v _(2)) = sqrt ((T _(1))/( 4 T _(1)) implies v _(2) = 2v _(1)` `therefore ` Wave speed will become DOUBLED. |
