Question $2(1$ point$)$

Waves on a String: A string of length $-L$ is under tension, and the speed of a wave in the string is $v.$ What will $$e the speed of a wave in the string if the length is increased to $2L$ but with no change in the mass or tension?

$\frac{v}{2}$

$\frac{v}{\sqrt[\phantom{2}]{2}}$

$w^2$

$2v$

$4v$
