Question 474: Waves

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

Accepted Answer

We know, velocity of transverse wave
$$v = \sqrt {{T \over \mu }} $$
$$	herefore$$ $${v_i} = \sqrt {{T \over \mu }} $$ and $${v_f} = \sqrt {{{2T} \over \mu }} $$
$$	herefore$$ $${{{v_i}} \over {{v_f}}} = {1 \over {\sqrt 2 }}$$
