Homework Statement
I am really confused.
v = λ f
doesn't that imply that speed is dependent on frequency?
There is a question in my book that says:
A sinusoidal wave of frequency f is traveling along a stretched string. The string is brought to rest, and a second traveling wave of frequency 2f is established on the string.
(i) what is the wave speed of the second wave?
Homework Equations
v = λ f
The Attempt at a Solution
so I figured the answer would be something like:
since v1=λf
it follows that, if the second wave has frequency 2f
v2 = λ(2f)
v2 = 2 (λf)
v2 = 2 (v1)
but somehow the answer is: "the same as the first wave" Can someone explain this to me?
