1. The problem statement, all variables and given/known data
A sinusodial wave is moving along a string of uniform density. If you double the frequency of the wave,

a)the speed of the wave doubles
b)the speed of the wave remains about the same


2. Relevant equations
v=lambda*f


3. The attempt at a solution
I chose a) using the equation v=lambda*f. as f doubles, v doubles too.

That would only be true if the wavelength remained the same.

What determines the speed of a wave on a string?
