Homework Statement
a flexible wire is 80 cm long has a mass of 0.40g. It is stretched across stops on a sonometer that are 50 cm apart by a force of 500N. Find the fundamental frequency with which the wire may vibrate. If it vibrates in 2 third overtone, what is it's frequency?
Homework Equations
[tex]f=\frac{1}{2L}\sqrt{\frac{T}{\frac{m}{L}}}[/tex]
The Attempt at a Solution
I don't kno where to start. I substituted all the given data. And I'm not really sure about my answer.
I can't decide what length should be used in the equation. the problem states the total length of the wire and the length of the wire which is streched on the sonometer.
