You set up two wires with different linear mass densities, as shown below. Wire A has a linear mass density of 0.15 kg/m. The linear mass density of wire B is 0.05 kg/m. If two waves are simultaneously sent through the wires and are to arrive simultaneously on the opposite end, calculate the required wire lengths L_A and L_B.

• A. L_A = 2.22 m
  L_B = 1.28m
• B. L_A = 0.88 m
  L_B = 2.63 m
• C. L_A = 2.63 m
  L_B = 0.88 m
• D. L_A = 1.28 m
  L_B = 2.22 m
• E. L_A = 2.22 m
  L_B = 0.88 m
• F. L_A = 0.88 m
  L_B = 2.22 m
• G. L_A = 1.28 m
  L_B = 2.63 m
• H. L_A = 2.63 m
  L_B = 1.28 m
