Speed of Waves

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

Show answer and solution

Answer: (c)

  1. v∝Tv \propto \sqrt{T}
  2. vivf=T2T=12\dfrac{v_i}{v_f} = \sqrt{\dfrac{T}{2T}} = \dfrac{1}{\sqrt{2}}
  3. So the answer is (c) 1:21:\sqrt{2}.
