In a resonance tube, closed at one end by a smooth moving piston and the other end open, exhibits the first three resonance lengths, L1, L2 and L3 for the same tuning fork. Then they are related by

  • (A):L3 = 2L2 = 4 L1
  • (B):
  • (C):(L3 - L2) = (L2 - L1)
  • (D):(L3 - L2) = 2(L2 - L1)

Best Answer

Correct Answer:

(C): (L3 - L2) = (L2 - L1)
