QUESTION #43 Wave on a String
Two strings (A, B) having linear densities μA = 2 × 10⁻⁴ kg/m and μB = 4 × 10⁻⁴ kg/m and lengths LA = 2.5 m and LB = 1.5 m respectively are joined. Free ends of A and B are tied to two rigid supports C and D, respectively creating a tension of 500 N in the wire. Two identical pulses, sent from C and D ends, take time t₁ and t₂ , respectively, to reach the joint. The ratio t₁/t₂ is :
