A metal wire with volume density `rho` and young\'s modulus `Y` is stretched between rigid supports. At temperature `T`, the speed of a transverse wave is found to be `v_(1)`. When temperature decreases `T - DeltaT`, the speed increases to `v_(2)`. Datermine coefficient of linear expansion of wire.
