Imagine you are holding a long rope under tension attached to a distant support. You can generate periodic waves by shaking the end up and down. Changing which of the following will least affect the velocity of waves along the string?

Question

Quizplus · Accepted Answer

The velocity of waves on a string is determined by the tension in the string and the mass per unit length of the string, according to the formula $v = \sqrt{\frac{T}{\mu}}$, where $v$ is the velocity, $T$ is the tension, and $\mu$ is the mass per unit length. The frequency of the waves you generate by shaking the rope does not directly affect the velocity of the waves; it affects the wavelength instead.
