1.	A steel wire of length 1 m, mass 0.1 kg and uniform cross sectional area10^(-6)m^(2) is rigidly fixed at two ends. The temperature of the wire is lowered by 20^(@) C . If transverse waves are now set up by lucking the string at the middle, calculate the frequency of the fundamental tone.Givne, for steel, co-efficient of linear expansion = 1.21 xx 10^(-5_(@))C^(1)and Young's modulus= 2 xx 10 ^(11) N* m^(-2) .
