Question

If the initial tension on a stretched string is doubled, then the ratio of the initial and final speeds of a transverse wave along the string is:, 2 : 1, 1 : 2, 1 : 2, 1 : 1

Case 1: T 1 = T Case 2: T 2 = 2 T We know, speed of transverse wave is related to tension by v = T μ , here, μ is mass per unit length of the string. ∴ v 1 v 2 = T 1 T 2 = T 2 T = 1 2 = 1 : 2
