A rod of length 0.3 m having variable linear mass density from A to B as λ = λ0 x(x is distance from A in meter), where λ0 = 100 kg/m2 is suspended by two light wires of same length. Ratio of their linear mass density is 2 : 9. Then which of the following is/are correct :
(A) Ratio of wave speed in wire–1 to wire–2 is 3 : 2
(B) Ratio of wave speed in wire–1 to wire–2 is 3 : 1
(C) Second harmonic in wire–1 has same frequency as third harmonic in wire–2
(D) Third overtone in wire–1 has same frequency as fifth overtone in wire–2
